- * \section definition Definition
- * 
- * Alpha_complex is a <a target="_blank" href="https://en.wikipedia.org/wiki/Simplicial_complex">simplicial complex</a>
- * constructed from the finite cells of a Delaunay Triangulation.
- * 
- * The filtration value of each simplex is computed as the square of the circumradius of the simplex if the
- * circumsphere is empty (the simplex is then said to be Gabriel), and as the minimum of the filtration
- * values of the codimension 1 cofaces that make it not Gabriel otherwise.
- * 
- * All simplices that have a filtration value strictly greater than a given alpha squared value are not inserted into
- * the complex.
- * 
- * \image html "alpha_complex_representation.png" "Alpha-complex representation"
- * 
- * Alpha_complex is constructing a <a target="_blank"
- * href="http://doc.cgal.org/latest/Triangulation/index.html#Chapter_Triangulations">Delaunay Triangulation</a>
- * \cite cgal:hdj-t-15b from <a target="_blank" href="http://www.cgal.org/">CGAL</a> (the Computational Geometry
- * Algorithms Library \cite cgal:eb-15b) and is able to create a `SimplicialComplexForAlpha`.
- * 
- * The complex is a template class requiring an Epick_d <a target="_blank"
- * href="http://doc.cgal.org/latest/Kernel_d/index.html#Chapter_dD_Geometry_Kernel">dD Geometry Kernel</a>
- * \cite cgal:s-gkd-15b from CGAL as template parameter.
- * 
- * \remark
- * - When the simplicial complex is constructed with an infinite value of alpha, the complex is a Delaunay
- * complex.
- * - For people only interested in the topology of the \ref alpha_complex (for instance persistence),
- * \ref alpha_complex is equivalent to the \ref cech_complex and much smaller if you do not bound the radii.
- * \ref cech_complex can still make sense in higher dimension precisely because you can bound the radii.
- *
- * \section pointsexample Example from points
- * 
- * This example builds the Delaunay triangulation from the given points in a 2D static kernel, and creates a
- * `Simplex_tree` with it.
- * 
- * Then, it is asked to display information about the simplicial complex.
- * 
- * \include Alpha_complex/Alpha_complex_from_points.cpp
- * 
- * When launching:
- * 
- * \code $> ./Alpha_complex_example_from_points
- * \endcode
- *
- * the program output is:
- * 
- * \include Alpha_complex/alphaoffreader_for_doc_60.txt
- * 
- * \section createcomplexalgorithm Create complex algorithm
- * 
- * \subsection datastructure Data structure
- * 
- * In order to create the simplicial complex, first, it is built from the cells of the Delaunay Triangulation.
- * The filtration values are set to NaN, which stands for unknown value.
- * 
- * In example, :
- * \image html "alpha_complex_doc.png" "Simplicial complex structure construction example"
- *
- * \subsection filtrationcomputation Filtration value computation algorithm

- * \f$
- *
- * \subsubsection dimension2 Dimension 2
- * 
- * From the example above, it means the algorithm looks into each triangle ([0,1,2], [0,2,4], [1,2,3], ...),
- * computes the filtration value of the triangle, and then propagates the filtration value as described
- * here :
- * \image html "alpha_complex_doc_420.png" "Filtration value propagation example"
- * 
- * \subsubsection dimension1 Dimension 1
- * 
- * Then, the algorithm looks into each edge ([0,1], [0,2], [1,2], ...),
- * computes the filtration value of the edge (in this case, propagation will have no effect).
- * 
- * \subsubsection dimension0 Dimension 0
- * 
- * Finally, the algorithm looks into each vertex ([0], [1], [2], [3], [4], [5] and [6]) and
- * sets the filtration value (0 in case of a vertex - propagation will have no effect).
- * 
- * \subsubsection nondecreasing Non decreasing filtration values
- * 
- * As the squared radii computed by CGAL are an approximation, it might happen that these alpha squared values do not
- * quite define a proper filtration (i.e. non-decreasing with respect to inclusion).
- * We fix that up by calling `SimplicialComplexForAlpha::make_filtration_non_decreasing()`.
- * 
- * \subsubsection pruneabove Prune above given filtration value
- * 
- * The simplex tree is pruned from the given maximum alpha squared value (cf.
- * `SimplicialComplexForAlpha::prune_above_filtration()`).
- * In the following example, the value is given by the user as argument of the program.
- * 
- * 
- * \section offexample Example from OFF file
- * 
- * This example builds the Delaunay triangulation in a dynamic kernel, and initializes the alpha complex with it.
- * 
- * 
- * Then, it is asked to display information about the alpha complex.
- * 
- * \include Alpha_complex/Alpha_complex_from_off.cpp
- * 
- * When launching:
- * 
- * \code $> ./Alpha_complex_example_from_off ../../data/points/alphacomplexdoc.off 32.0
- * \endcode
- *
- * the program output is:
- * 
- * \include Alpha_complex/alphaoffreader_for_doc_32.txt

-
- * Bitmap_cubical_complex is an example of a structured complex useful in computational mathematics (specially rigorous
- * numerics) and image analysis. The presented implementation of cubical complexes is based on the following
- * definition.
- *
- * An <em>elementary interval</em> is an interval of a form \f$ [n,n+1] \f$, or \f$[n,n]\f$, for \f$ n \in \mathcal{Z}
- * \f$. The first one is called <em>non-degenerate</em>, while the second one is \a degenerate interval. A
- * <em>boundary of a elementary interval</em> is a chain  \f$\partial [n,n+1] = [n+1,n+1]-[n,n] \f$ in case of
- * non-degenerated elementary interval and \f$\partial [n,n] = 0 \f$ in case of degenerate elementary interval. An
- * <em>elementary cube</em> \f$ C \f$ is a product of elementary intervals, \f$C=I_1 \times \ldots \times I_n\f$.
- * <em>Embedding dimension</em> of a cube is n, the number of elementary intervals (degenerate or not) in the product.
- * A <em>dimension of a cube</em> \f$C=I_1 \times ... \times I_n\f$ is the number of non degenerate elementary
- * intervals in the product. A <em>boundary of a cube</em> \f$C=I_1 \times \ldots \times I_n\f$ is a chain obtained
- * in the following way:
- * \f[\partial C = (\partial I_1 \times \ldots \times I_n) + (I_1 \times \partial I_2 \times \ldots \times I_n) +
- * \ldots + (I_1 \times I_2 \times \ldots \times \partial I_n).\f]
- * A <em>cubical complex</em> \f$\mathcal{K}\f$ is a collection of cubes closed under operation of taking boundary
- * (i.e. boundary of every cube from the collection is in the collection). A cube \f$C\f$ in cubical complex
- * \f$\mathcal{K}\f$ is <em>maximal</em> if it is not in a boundary of any other cube in \f$\mathcal{K}\f$. A \a
- * support of a cube \f$C\f$ is the set in \f$\mathbb{R}^n\f$ occupied by \f$C\f$ (\f$n\f$ is the embedding dimension
- * of \f$C\f$).
- *
- * Cubes may be equipped with a filtration values in which case we have filtered cubical complex. All the cubical
- * complexes considered in this implementation are filtered cubical complexes (although, the range of a filtration may
- * be a set of two elements).
- *
- * For further details and theory of cubical complexes, please consult \cite kaczynski2004computational as well as the
- * following paper \cite peikert2012topological .
- *
- * \section cubicalcomplexdatastructure Data structure
- *
- * The implementation of Cubical complex provides a representation of complexes that occupy a rectangular region in
- * \f$\mathbb{R}^n\f$. This extra assumption allows for a memory efficient way of storing cubical complexes in a form
- * of so called bitmaps. Let \f$R = [b_1,e_1] \times \ldots \times [b_n,e_n]\f$, for \f$b_1,...b_n,e_1,...,e_n \in
- * \mathbb{Z}\f$, \f$b_i \leq d_i\f$ be the considered rectangular region and let \f$\mathcal{K}\f$ be a filtered
- * cubical complex having the rectangle \f$R\f$ as its support. Note that the structure of the coordinate system gives
- * a way a lexicographical ordering of cells of \f$\mathcal{K}\f$. This ordering is a base of the presented
- * bitmap-based implementation. In this implementation, the whole cubical complex is stored as a vector of the values
- * of filtration. This, together with dimension of \f$\mathcal{K}\f$ and the sizes of \f$\mathcal{K}\f$ in all
- * directions, allows to determine, dimension, neighborhood, boundary and coboundary of every cube \f$C \in
- * \mathcal{K}\f$.
- *
- * \image html "Cubical_complex_representation.png" Cubical complex.
- *
- * Note that the cubical complex in the figure above is, in a natural way, a product of one dimensional cubical
- * complexes in \f$\mathbb{R}\f$. The number of all cubes in each direction is equal \f$2n+1\f$, where \f$n\f$ is the
- * number of maximal cubes in the considered direction. Let us consider a cube at the position \f$k\f$ in the bitmap.
- * Knowing the sizes of the bitmap, by a series of modulo operation, we can determine which elementary intervals are
- * present in the product that gives the cube \f$C\f$. In a similar way, we can compute boundary and the coboundary of
- * each cube. Further details can be found in the literature.
- *
- * \section inputformat Input Format
- *
- * In the current implantation, filtration is given at the maximal cubes, and it is then extended by the lower star
- * filtration to all cubes. There are a number of constructors that can be used to construct cubical complex by users
- * who want to use the code directly. They can be found in the \a Bitmap_cubical_complex class.
- * Currently one input from a text file is used. It uses a format used already in Perseus software
- * (http://www.sas.upenn.edu/~vnanda/perseus/) by Vidit Nanda. The file format is described here: \ref FileFormatsPerseus.
- *
- * \section PeriodicBoundaryConditions Periodic boundary conditions
- * Often one would like to impose periodic boundary conditions to the cubical complex. Let \f$ I_1\times ... \times
- * I_n \f$ be a box that is decomposed with a cubical complex \f$ \mathcal{K} \f$. Imposing periodic boundary
- * conditions in the direction i, means that the left and the right side of a complex \f$ \mathcal{K} \f$ are
- * considered the same. In particular, if for a bitmap \f$ \mathcal{K} \f$ periodic boundary conditions are imposed
- * in all directions, then complex \f$ \mathcal{K} \f$ became n-dimensional torus. One can use various constructors
- * from the file Bitmap_cubical_complex_periodic_boundary_conditions_base.h to construct cubical complex with periodic
- * boundary conditions. One can also use Perseus style input files (see \ref FileFormatsPerseus).
- *
- * \section BitmapExamples Examples
- * End user programs are available in example/Bitmap_cubical_complex and utilities/Bitmap_cubical_complex folders.

- * \section cechdefinition Čech complex definition
- * 
- * Čech complex
- * <a target="_blank" href="https://en.wikipedia.org/wiki/%C4%8Cech_cohomology">(Wikipedia)</a> is a
- * <a target="_blank" href="https://en.wikipedia.org/wiki/Simplicial_complex">simplicial complex</a> constructed
- *  from a proximity graph. The set of all simplices is filtered by the radius of their minimal enclosing ball.
- *
- * The input shall be a point cloud in an Euclidean space.
- * 
- * \remark For people only interested in the topology of the \ref cech_complex (for instance persistence),
- * \ref alpha_complex is equivalent to the \ref cech_complex and much smaller if you do not bound the radii.
- * \ref cech_complex can still make sense in higher dimension precisely because you can bound the radii.
- *
- * \subsection cechalgorithm Algorithm
- *
- * Cech_complex first builds a proximity graph from a point cloud.
- * The filtration value of each edge of the `Gudhi::Proximity_graph` is computed from
- * `Gudhi::Minimal_enclosing_ball_radius` function.
- * 
- * All edges that have a filtration value strictly greater than a user given maximal radius value, \f$max\_radius\f$,
- * are not inserted into the complex.
- * 
- * Vertex name correspond to the index of the point in the given range (aka. the point cloud).
- * 
- * \image html "cech_one_skeleton.png" "Čech complex proximity graph representation"
- * 
- * When creating a simplicial complex from this proximity graph, Cech_complex inserts the proximity graph into the
- * simplicial complex data structure, and then expands the simplicial complex when required.
- *
- * On this example, as edges \f$(x,y)\f$, \f$(y,z)\f$ and \f$(z,y)\f$ are in the complex, the minimal ball radius
- * containing the points \f$(x,y,z)\f$ is computed.
- *
- * \f$(x,y,z)\f$ is inserted to the simplicial complex with the filtration value set with
- * \f$mini\_ball\_radius(x,y,z))\f$ iff \f$mini\_ball\_radius(x,y,z)) \leq max\_radius\f$.
- *
- * And so on for higher dimensions.
- *
- * \image html "cech_complex_representation.png" "Čech complex expansion"
- *
- * The minimal ball radius computation is insured by
- * <a target="_blank" href="https://people.inf.ethz.ch/gaertner/subdir/software/miniball.html">
- * the miniball software (V3.0)</a> - Smallest Enclosing Balls of Points - and distributed with GUDHI.
- * Please refer to
- * <a target="_blank" href="https://people.inf.ethz.ch/gaertner/subdir/texts/own_work/esa99_final.pdf">
- * the miniball software design description</a> for more information about this computation.
- *
- * This radius computation is the reason why the Cech_complex is taking much more time to be computed than the
- * \ref rips_complex but it offers more topological guarantees.
- *
- * If the Cech_complex interfaces are not detailed enough for your need, please refer to
- * <a href="_cech_complex_2cech_complex_step_by_step_8cpp-example.html">
- * cech_complex_step_by_step.cpp</a> example, where the graph construction over the Simplex_tree is more detailed.
- *
- * \subsection cechpointscloudexample Example from a point cloud
- * 
- * This example builds the proximity graph from the given points, and maximal radius values.
- * Then it creates a `Simplex_tree` with it.
- * 
- * Then, it is asked to display information about the simplicial complex.
- * 
- * \include Cech_complex/cech_complex_example_from_points.cpp
- * 
- * When launching (maximal enclosing ball radius is 1., is expanded until dimension 2):
- * 
- * \code $> ./Cech_complex_example_from_points
- * \endcode
- *
- * the program output is:
- * 
- * \include Cech_complex/cech_complex_example_from_points_for_doc.txt

-/**  \defgroup cover_complex Cover complex
- * 
- * \author    Mathieu Carrière
- * 
- * @{
- * 
- * Visualizations of the simplicial complexes can be done with either
- * neato (from <a target="_blank" href="http://www.graphviz.org/">graphviz</a>),
- * <a target="_blank" href="http://www.geomview.org/">geomview</a>,
- * <a target="_blank" href="https://github.com/MLWave/kepler-mapper">KeplerMapper</a>.
- * Input point clouds are assumed to be
- * <a target="_blank" href="http://www.geomview.org/docs/html/OFF.html">OFF files</a>.
- *
- * \section covers Covers
- *
- * Nerves and Graph Induced Complexes require a cover C of the input point cloud P,
- * that is a set of subsets of P whose union is P itself.
- * Very often, this cover is obtained from the preimage of a family of intervals covering
- * the image of some scalar-valued function f defined on P. This family is parameterized
- * by its resolution, which can be either the number or the length of the intervals,
- * and its gain, which is the overlap percentage between consecutive intervals (ordered by their first values).
- *
- * \section nerves Nerves
- *
- * \subsection nervedefinition Nerve definition
- *
- * Assume you are given a cover C of your point cloud P. Then, the Nerve of this cover
- * is the simplicial complex that has one k-simplex per k-fold intersection of cover elements.
- * See also <a target="_blank" href="https://en.wikipedia.org/wiki/Nerve_of_a_covering"> Wikipedia </a>.
- *
- * \image html "nerve.png" "Nerve of a double torus"
- *
- * \subsection nerveexample Example
- *
- * This example builds the Nerve of a point cloud sampled on a 3D human shape (human.off).
- * The cover C comes from the preimages of intervals (10 intervals with gain 0.3)
- * covering the height function (coordinate 2),
- * which are then refined into their connected components using the triangulation of the .OFF file.
- *
- * \include Nerve_GIC/Nerve.cpp
- *
- * When launching:
- *
- * \code $> ./Nerve ../../data/points/human.off 2 10 0.3 -v
- * \endcode
- *
- * the program output is:
- *
- * \include Nerve_GIC/Nerve.txt
- *
- * The program also writes a file ../../data/points/human_sc.txt. The first three lines in this file are the location
- * of the input point cloud and the function used to compute the cover.
- * The fourth line contains the number of vertices nv and edges ne of the Nerve.
- * The next nv lines represent the vertices. Each line contains the vertex ID,
- * the number of data points it contains, and their average color function value.
- * Finally, the next ne lines represent the edges, characterized by the ID of their vertices.
- *
- * Using KeplerMapper, one can obtain the following visualization:
- *
- * \image html "nervevisu.jpg" "Visualization with KeplerMapper"
- *
- * \section gic Graph Induced Complexes (GIC)
- *
- * \subsection gicdefinition GIC definition
- *
- * Again, assume you are given a cover C of your point cloud P. Moreover, assume
- * you are also given a graph G built on top of P. Then, for any clique in G
- * whose nodes all belong to different elements of C, the GIC includes a corresponding
- * simplex, whose dimension is the number of nodes in the clique minus one.
- * See \cite Dey13 for more details.
- *
- * \image html "GIC.jpg" "GIC of a point cloud."
- *
- * \subsection gicexamplevor Example with cover from Voronoï
- *
- * This example builds the GIC of a point cloud sampled on a 3D human shape (human.off).
- * We randomly subsampled 100 points in the point cloud, which act as seeds of
- * a geodesic Voronoï diagram. Each cell of the diagram is then an element of C.
- * The graph G (used to compute both the geodesics for Voronoï and the GIC)
- * comes from the triangulation of the human shape. Note that the resulting simplicial complex is in dimension 3
- * in this example.
- *
- * \include Nerve_GIC/VoronoiGIC.cpp
- *
- * When launching:
- *
- * \code $> ./VoronoiGIC ../../data/points/human.off 700 -v
- * \endcode
- *
- * the program outputs SC.off. Using e.g.
- *
- * \code $> geomview ../../data/points/human_sc.off
- * \endcode
- *
- * one can obtain the following visualization:
- *
- * \image html "gicvoronoivisu.jpg" "Visualization with Geomview"
- *
- * \subsection functionalGICdefinition Functional GIC
- *
- * If one restricts to the cliques in G whose nodes all belong to preimages of consecutive
- * intervals (assuming the cover of the height function is minimal, i.e. no more than
- * two intervals can intersect at a time), the GIC is of dimension one, i.e. a graph.
- * We call this graph the functional GIC. See \cite Carriere16 for more details.
- *
- * \subsection functionalGICexample Example
- *
- * Functional GIC comes with automatic selection of the Rips threshold,
- * the resolution and the gain of the function cover. See \cite Carriere17c for more details. In this example,
- * we compute the functional GIC of a Klein bottle embedded in R^5,
- * where the graph G comes from a Rips complex with automatic threshold,
- * and the cover C comes from the preimages of intervals covering the first coordinate,
- * with automatic resolution and gain. Note that automatic threshold, resolution and gain
- * can be computed as well for the Nerve.
- *
- * \include Nerve_GIC/CoordGIC.cpp
- *
- * When launching:
- *
- * \code $> ./CoordGIC ../../data/points/KleinBottle5D.off 0 -v
- * \endcode
- *
- * the program outputs SC.dot. Using e.g.
- *
- * \code $> neato SC.dot -Tpdf -o SC.pdf
- * \endcode
- *
- * one can obtain the following visualization:
- *
- * \image html "coordGICvisu2.jpg" "Visualization with Neato"
- *
- * where nodes are colored by the filter function values and, for each node, the first number is its ID
- * and the second is the number of data points that its contain.
- *
- * We also provide an example on a set of 72 pictures taken around the same object (lucky_cat.off).
- * The function is now the first eigenfunction given by PCA, whose values
- * are written in a file (lucky_cat_PCA1). Threshold, resolution and gain are automatically selected as before.
- *
- * \include Nerve_GIC/FuncGIC.cpp
- *
- * When launching:
- *
- * \code $> ./FuncGIC ../../data/points/COIL_database/lucky_cat.off ../../data/points/COIL_database/lucky_cat_PCA1 -v
- * \endcode
- *
- * the program outputs again SC.dot which gives the following visualization after using neato:
- *
- * \image html "funcGICvisu.jpg" "Visualization with neato"

- In order to perform most of the statistical tests and machine learning algorithms on a data one need to be able to
- perform only a very limited number of operations on them. Let us fix a representation of
- data of a type A. To perform most of the statistical and machine learning operations one need to be able to compute
- average of objects of type A (so that the averaged object is also of a type A), to
- compute distance between objects of a type A, to vectorize object of a type A and to compute scalar product of a pair
- objects of a type A.
-
- To put this statement into a context, let us assume we have two collections \f$ c_1,\ldots,c_n\f$ and
- \f$d_1,...,d_n\f$ of objects of a type A. We want to verify if the average of those two collections
- are different by performing a permutation test.
- First of all, we compute averages of those two collections: C average of \f$ c_1,\ldots,c_n \f$ and D average of
- \f$d_1,\ldots,d_n\f$. Note that both C and D are of a type A. Then we compute \f$d(C,D)\f$,
- a distance between C and D.
- Later we put the two collections into one bin:
- \f[B = \{ c_1,...,c_n,d_1,...,d_n \}\f]
- Then we shuffle B, and we divide the shuffled version of B into two classes: \f$B_1\f$ and \f$B_2\f$ (in this case, of
- the same cardinality). Then we compute averages \f$\hat{B_1}\f$ and \f$\hat{B_2}\f$
- of elements in \f$B_1\f$ and \f$B_2\f$. Note that again, \f$\hat{B_1}\f$ and \f$\hat{B_2}\f$ are of a type A.
- Then we compute their distance \f$d(\hat{B_1},\hat{B_2})\f$. The procedure of shuffling and dividing the set \f$B\f$
- is repeated \f$N\f$ times (where \f$N\f$ is reasonably large number).
- Then the p-value of a statement that the averages of  \f$c_1,...,c_n\f$ and \f$d_1,...,d_n\f$ is approximated by the
- number of times \f$d(\hat{B_1},\hat{B_2}) > d(C,D)\f$ divided by \f$N\f$.
-
- The permutation test reminded above can be performed for any type A which can be averaged, and which allows for
- computations of distances.
-
- The Persistence\_representations contains a collection of various representations of persistent homology that
- implements various concepts described below:
-
- \li Concept of a representation of persistence that allows averaging (so that the average object is of the same type).
- \li Concept of representation of persistence that allows computations of distances.
- \li Concept of representation of persistence that allows computations of scalar products.
- \li Concept of representation of persistence that allows vectorization.
- \li Concept of representation of persistence that allows computations of real-valued characteristics of objects.
-
-
- At the moment an implementation of the following representations of persistence are available (further details of
- those representations will be discussed later):
-
- \li Exact persistence landscapes (allow averaging, computation of distances, scalar products, vectorizations and real
- value characteristics).
- \li Persistence landscapes on a grid (allow averaging, computation of distances scalar products, vectorizations and
- real value characteristics).
- \li Persistence heat maps – various representations where one put some weighted or not Gaussian kernel for each point
- of diagram (allow averaging, computation of distances, scalar products,
- vectorizations and real value characteristics).
- \li Persistence vectors (allow averaging, computation of distances, scalar products, vectorizations and real value
- characteristics).
- \li Persistence diagrams / barcodes (allow computation of distances, vectorizations and real value characteristics).
-
-
- Note that at the while functionalities like averaging, distances and scalar products are fixed, there is no canonical
- way of vectorizing and computing real valued characteristics of objects. Therefore the
- vectorizations and computation of real value characteristics procedures are quite likely to evolve in the furthering
- versions of the library.
-
- The main aim of this implementation is to be able to implement various statistical methods, both on the level of C++
- and on the level of python. The methods will operate on the functionalities offered
- by concepts. That means that the statistical and ML methods will be able to operate on any representation that
- implement the required concept (including the ones that are not in the library at the moment).
- That gives provides a framework, that is very easy to extend, for topological statistics.
-
- Below we are discussing the representations which are currently implemented in Persistence\_representations package:
-
- \section sec_persistence_landscapes Persistence Landscapes
- <b>Reference manual:</b> \ref Gudhi::Persistence_representations::Persistence_landscape <br>
- Persistence landscapes were originally proposed by Bubenik in \cite bubenik_landscapes_2015. Efficient algorithms to
- compute them rigorously were proposed by Bubenik and Dlotko in \cite bubenik_dlotko_landscapes_2016. The idea of
- persistence landscapes is shortly summarized in below.
-
- To begin with, suppose we are given a point \f$(b,d) \in \mathbb{R}^2\f$ in a
- persistence diagram. With this point, we associate a piecewise
- linear function \f$f_{(b,d)} : \mathbb{R} \rightarrow [0,\infty)\f$, which is
- defined as
-
-  \f[f_{(b,d)}(x) =
-  \left\{ \begin{array}{ccl}
-            0     & \mbox{ if } & x \not\in (b, d) \; , \\
-            x - b & \mbox{ if } & x \in \left( b, \frac{b+d}{2}
-              \right] \; , \\
-            d - x & \mbox{ if } & x \in \left(\frac{b+d}{2},
-              d \right) \; .
-  \end{array} \right.
- \f]
-
- A persistence landscape of the birth-death
- pairs \f$(b_i , d_i)\f$, where \f$i = 1,\ldots,m\f$, which constitute the given
- persistence diagram is the sequence of functions \f$\lambda_k : \mathbb{R} \rightarrow [0,\infty)\f$ for \f$k \in
- \mathbb{N}\f$, where \f$\lambda_k(x)\f$
- denotes the \f$k^{\rm th}\f$ largest value of the numbers \f$f_{(b_i,d_i)}(x)\f$,
- for \f$i = 1, \ldots, m\f$, and we define \f$\lambda_k(x) = 0\f$ if \f$k > m\f$.
- Equivalently, this sequence of functions can be combined into a single
- function \f$L : \mathbb{N} \times \mathbb{R} \to [0,\infty)\f$ of two
- variables, if we define \f$L(k,t) = \lambda_k(t)\f$.
-
- The detailed description of algorithms used to compute persistence landscapes can be found in
- \cite bubenik_dlotko_landscapes_2016.
- Note that this implementation provides exact representation of landscapes. That have many advantages, but also a few
- drawbacks. For instance, as discussed
- in \cite bubenik_dlotko_landscapes_2016, the exact representation of landscape may be of quadratic size with respect
- to the input persistence diagram. It may therefore happen
- that, for very large diagrams, using this representation may be memory--prohibitive. In such a case, there are two
- possible ways to proceed:
-
- \li Use non exact representation on a grid described in the Section \ref sec_landscapes_on_grid.
- \li Compute just a number of initial nonzero landscapes. This option is available from C++ level as a last parameter of
- the constructor of persistence landscape (set by default to std::numeric_limits<size_t>::max()).
-
-
-
- \section sec_landscapes_on_grid Persistence Landscapes on a grid
- <b>Reference manual:</b> \ref Gudhi::Persistence_representations::Persistence_landscape_on_grid <br>
- This is an alternative, not--exact, representation of persistence landscapes defined in the Section \ref
- sec_persistence_landscapes. Unlike in the Section \ref sec_persistence_landscapes we build a
- representation of persistence landscape by sampling its values on a finite, equally distributed grid of points.
- Since, the persistence landscapes that originate from persistence diagrams have slope \f$1\f$ or \f$-1\f$, we have an
- estimate of a region between the grid points where the landscape cab be located.
- That allows to estimate an error make when performing various operations on landscape. Note that for average
- landscapes the slope is in range \f$[-1,1]\f$ and similar estimate can be used.
-
- Due to a lack of rigorous description of the algorithms to deal with this non--rigorous representation of persistence
- landscapes in the literature, we are providing a short discussion of them in below.
-
- Let us assume that we want to compute persistence landscape on a interval \f$[x,y]\f$. Let us assume that we want to
- use \f$N\f$ grid points for that purpose.
- Then we will sample the persistence landscape on points \f$x_1 = x , x_2 = x + \frac{y-x}{N}, \ldots , x_{N} = y\f$.
- Persistence landscapes are represented as a vector of
- vectors of real numbers. Assume that i-th vector consist of \f$n_i\f$ numbers sorted from larger to smaller. They
- represent the values of the functions
- \f$\lambda_1,\ldots,\lambda_{n_i}\f$ ,\f$\lambda_{n_i+1}\f$ and the functions with larger indices are then zero
- functions) on the i-th point of a grid, i.e. \f$x + i \frac{y-x}{N}\f$.
-
- When averaging two persistence landscapes represented by a grid we need to make sure that they are defined in a
- compatible grids. I.e. the intervals \f$[x,y]\f$ on which they are defined are
- the same, and the numbers of grid points \f$N\f$ are the same in both cases. If this is the case, we simply compute
- point-wise averages of the entries of corresponding
- vectors (In this whole section we assume that if one vector of numbers is shorter than another, we extend the shorter
- one with zeros so that they have the same length.)
-
- Computations of distances between two persistence landscapes on a grid is not much different than in the rigorous
- case. In this case, we sum up the distances between the same levels of
- corresponding landscapes. For fixed level, we approximate the landscapes between the corresponding constitutive
- points of landscapes by linear functions, and compute the \f$L^p\f$ distance between them.
-
- Similarly as in case of distance, when computing the scalar product of two persistence landscapes on a grid, we sum up
- the scalar products of corresponding levels of landscapes. For each level,
- we assume that the persistence landscape on a grid between two grid points is approximated by linear function.
- Therefore to compute scalar product of two corresponding levels of landscapes,
- we sum up the integrals of products of line segments for every pair of constitutive grid points.
-
- Note that for this representation we need to specify a few parameters:
-
- \li Begin and end point of a grid -- the interval \f$[x,y]\f$ (real numbers).
- \li Number of points in a grid (positive integer \f$N\f$).
-
-
- Note that the same representation is used in TDA R-package \cite Fasy_Kim_Lecci_Maria_tda.
-
- \section sec_persistence_heat_maps Persistence heat maps
- <b>Reference manual:</b> \ref Gudhi::Persistence_representations::Persistence_heat_maps <br>
- This is a general class of discrete structures which are based on idea of placing a kernel in the points of
- persistence diagrams.
- This idea appeared in work by many authors over the last 15 years. As far as we know this idea was firstly described
- in the work of Bologna group in \cite Ferri_Frosini_comparision_sheme_1 and \cite Ferri_Frosini_comparision_sheme_2.
- Later it has been described by Colorado State University group in \cite Persistence_Images_2017. The presented paper
- in the first time provide a discussion of stability of the representation.
- Also, the same ideas are used in construction of two recent kernels used for machine learning:
- \cite Kusano_Fukumizu_Hiraoka_PWGK and \cite Reininghaus_Huber_ALL_PSSK. Both the kernel's construction uses
- interesting ideas to ensure stability of the representation with respect to Wasserstein metric. In the kernel
- presented in \cite Kusano_Fukumizu_Hiraoka_PWGK, a scaling function is used to multiply the Gaussian kernel in the
- way that the points close to diagonal got low weight and consequently do not have a big influence on the resulting
- distribution. In \cite Reininghaus_Huber_ALL_PSSK for every point \f$(b,d)\f$ two Gaussian kernels
- are added: first, with a weight 1 in a point \f$(b,d)\f$, and the second, with the weight -1 for a point \f$(b,d)\f$.
- In both cases, the representations are stable with respect to 1-Wasserstein distance.
-
- In Persistence\_representations package we currently implement a discretization of the distributions described above.
- The base of this implementation is 2-dimensional array of pixels. Each pixel have assigned a real value which
- is a sum of values of distributions induced by each point of the persistence diagram. At the moment we compute the
- sum of values on a center of a pixels. It can be easily extended to any other function
- (like for instance sum of integrals of the intermediate distribution on a pixel).
-
- The parameters that determine the structure are the following:
-
- \li A positive integer k determining the size of the kernel we used (we always assume that the kernels are square).
- \li A filter: in practice a square matrix of a size \f$2k+1 \times 2k+1\f$. By default, this is a discretization of
- N(0,1) kernel.
- \li The box \f$[x_0,x_1]\times [y_0,y_1]\f$ bounding the domain of the persistence image.
- \li Scaling function. Each Gaussian kernel at point \f$(p,q)\f$ gets multiplied by the value of this function at the
- point \f$(p,q)\f$.
- \li A boolean value determining if the space below diagonal should be erased or not. To be precise: when points close
- to diagonal are given then sometimes the kernel have support that reaches the region
- below the diagonal. If the value of this parameter is true, then the values below diagonal can be erased.
-
-
- \section sec_persistence_vectors Persistence vectors
- <b>Reference manual:</b> \ref Gudhi::Persistence_representations::Vector_distances_in_diagram <br>
- This is a representation of persistent homology in a form of a vector which was designed for an application in 3d
- graphic in \cite Carriere_Oudot_Ovsjanikov_top_signatures_3d. Below we provide a short description of this
- representation.
-
- Given a persistence diagram \f$D = \{ (b_i,d_i) \}\f$, for every pair of birth--death points \f$(b_1,d_1)\f$ and
- \f$(b_2,d_2)\f$ we compute the following three distances:
-
- \li \f$d( (b_1,d_1) , (b_2,d_2) )\f$.
- \li \f$d( (b_1,d_1) , (\frac{b_1,d_1}{2},\frac{b_1,d_1}{2}) )\f$.
- \li \f$d( (b_2,d_2) , (\frac{b_2,d_2}{2},\frac{b_2,d_2}{2}) )\f$.
-
- We pick the smallest of those and add it to a vector. The obtained vector of numbers is then sorted in decreasing
- order. This way we obtain a persistence vector representing the diagram.
-
- Given two persistence vectors, the computation of distances, averages and scalar products is straightforward. Average
- is simply a coordinate-wise average of a collection of vectors. In this section we
- assume that the vectors are extended by zeros if they are of a different size. To compute distances we compute
- absolute value of differences between coordinates. A scalar product is a sum of products of
- values at the corresponding positions of two vectors.

-  Computation of persistent cohomology using the algorithm of 
-  \cite DBLP:journals/dcg/SilvaMV11 and \cite DBLP:journals/corr/abs-1208-5018 
-  and the Compressed Annotation Matrix 
-  implementation of \cite DBLP:conf/esa/BoissonnatDM13 
-       
-  The theory of homology consists in attaching to a topological space a sequence of 
-  (homology) groups, 
-  capturing global topological features 
-  like connected components, holes, cavities, etc. Persistent homology studies the evolution 
-  -- birth, life and death -- of 
-  these features when the topological space is changing. Consequently, the theory is essentially 
-  composed of three elements: 
-  topological spaces, their homology groups and an evolution scheme.
-
- \section persistencetopolocalspaces Topological Spaces
- Topological spaces are represented by simplicial complexes.
- Let \f$V = \{1, \cdots ,|V|\}\f$ be a set of <EM>vertices</EM>.
- A <EM>simplex</EM> \f$\sigma\f$ is a subset of vertices
- \f$\sigma \subseteq V\f$. A <EM>simplicial complex</EM> \f$\mathbf{K}\f$
- on \f$V\f$ is a collection of simplices \f$\{\sigma\}\f$,
- \f$\sigma \subseteq V\f$, such that \f$\tau \subseteq \sigma \in \mathbf{K}
- \Rightarrow \tau \in \mathbf{K}\f$. The dimension \f$n=|\sigma|-1\f$ of \f$\sigma\f$
- is its number of elements minus 1. A <EM>filtration</EM> of a simplicial complex is
- a function \f$f:\mathbf{K} \rightarrow \mathbb{R}\f$ satisfying \f$f(\tau)\leq
- f(\sigma)\f$ whenever \f$\tau \subseteq \sigma\f$.
-
- We define the concept FilteredComplex which enumerates the requirements for a class
- to represent a filtered complex from which persistent homology may be computed.
- We use the vocabulary of simplicial complexes, but the concept
- is valid for any type of cell complex. The main requirements
- are the definition of:
- \li type <CODE>Indexing_tag</CODE>, which is a model of the concept
- <CODE>IndexingTag</CODE>,
- describing the nature of the indexing scheme,
- \li type Simplex_handle to manipulate simplices,
- \li method <CODE>int dimension(Simplex_handle)</CODE> returning
- the dimension of a simplex,
- \li type and method <CODE>Boundary_simplex_range
- boundary_simplex_range(Simplex_handle)</CODE> that returns
- a range giving access to the codimension 1 subsimplices of the
- input simplex, as-well-as the coefficients \f$(-1)^i\f$ in the
- definition of the operator \f$\partial\f$. The iterators have
- value type <CODE>Simplex_handle</CODE>,
- \li type and method
- <CODE>Filtration_simplex_range filtration_simplex_range ()</CODE>
- that returns a range giving
- access to all the simplices of the complex read in the order
- assigned by the indexing scheme,
- \li type and method
- <CODE>Filtration_value filtration (Simplex_handle)</CODE> that returns the value of
- the filtration on the simplex represented by the handle.
-
- \section persistencehomology Homology
- For a ring \f$\mathcal{R}\f$, the group of <EM>n-chains</EM>,
- denoted \f$\mathbf{C}_n(\mathbf{K},\mathcal{R})\f$, of \f$\mathbf{K}\f$ is the
- group of formal sums of
- n-simplices with \f$\mathcal{R}\f$ coefficients. The <EM>boundary operator</EM> is a
- linear operator
- \f$\partial_n: \mathbf{C}_n(\mathbf{K},\mathcal{R}) \rightarrow \mathbf{C}_{n-1}(\mathbf{K},\mathcal{R})\f$
- such that \f$\partial_n \sigma = \partial_n [v_0, \cdots , v_n] =
- \sum_{i=0}^n (-1)^{i}[v_0,\cdots ,\widehat{v_i}, \cdots,v_n]\f$,
- where \f$\widehat{v_i}\f$ means \f$v_i\f$ is omitted from the list. The chain
- groups form a sequence:
-
- \f[\cdots \ \ \mathbf{C}_n(\mathbf{K},\mathcal{R}) \xrightarrow{\ \partial_n\ } \mathbf{C}_{n-1}(\mathbf{K},\mathcal{R})
- \xrightarrow{\partial_{n-1}} \cdots \xrightarrow{\ \partial_2 \ }
- \mathbf{C}_1(\mathbf{K},\mathcal{R}) \xrightarrow{\ \partial_1 \ }  \mathbf{C}_0(\mathbf{K},\mathcal{R}) \f]
-
- of finitely many groups \f$\mathbf{C}_n(\mathbf{K},\mathcal{R})\f$ and homomorphisms
- \f$\partial_n\f$, indexed by the dimension \f$n \geq 0\f$.
- The boundary operators satisfy the property \f$\partial_n \circ \partial_{n+1}=0\f$
- for every \f$n > 0\f$
- and we define the homology groups:
-
- \f[\mathbf{H}_n(\mathbf{K},\mathcal{R}) = \ker \partial_n / \mathrm{im} \  \partial_{n+1}\f]
-
- We refer to \cite Munkres-elementsalgtop1984 for an introduction to homology
- theory and to \cite DBLP:books/daglib/0025666 for an introduction to persistent homology.
-
- \section persistenceindexingscheme Indexing Scheme
- "Changing" a simplicial complex consists in applying a simplicial map.
- An <EM>indexing scheme</EM> is a directed graph together with a traversal
- order, such that two
- consecutive nodes in the graph are connected by an arrow (either forward or backward).
- The nodes represent simplicial complexes and the directed edges simplicial maps.
-
- From the computational point of view, there are two types of indexing schemes of
- interest
- in persistent homology: <EM>linear</EM> ones
- \f$\bullet \longrightarrow \bullet \longrightarrow \cdots \longrightarrow \bullet
- \longrightarrow \bullet\f$
- in persistent homology \cite DBLP:journals/dcg/ZomorodianC05 ,
- and <EM>zigzag</EM> ones
- \f$\bullet \longrightarrow \bullet \longleftarrow \cdots
- \longrightarrow \bullet
- \longleftarrow \bullet \f$ in zigzag persistent
- homology \cite DBLP:journals/focm/CarlssonS10.
- These indexing schemes have a natural left-to-right traversal order, and we
- describe them with ranges and iterators.
- In the current release of the Gudhi library, only the linear case is implemented.
-
- In the following, we consider the case where the indexing scheme is induced
- by a filtration.
- Ordering the simplices
- by increasing filtration values (breaking ties so as a simplex appears after
- its subsimplices of same filtration value) provides an indexing scheme.

- * \section ripsdefinition Rips complex definition
- * 
- * The Vietoris-Rips complex
- * <a target="_blank" href="https://en.wikipedia.org/wiki/Vietoris%E2%80%93Rips_complex">(Wikipedia)</a>
- * is an abstract simplicial complex
- * defined on a finite metric space, where each simplex corresponds to a subset
- * of point whose diameter is smaller that some given threshold.
- * Varying the threshold, we can also see the Rips complex as a filtration of
- * the \f$(n-1)-\f$dimensional simplex, where the filtration value of each
- * simplex is the diameter of the corresponding subset of points.
- *
- * This filtered complex is most often used as an approximation of the
- * Čech complex. After rescaling (Rips using the length of the edges and Čech
- * the half-length), they share the same 1-skeleton and are multiplicatively
- * 2-interleaved or better. While it is slightly bigger, it is also much
- * easier to compute.
- *
- * The number of simplices in the full Rips complex is exponential in the
- * number of vertices, it is thus usually restricted, by excluding all the
- * simplices with filtration value larger than some threshold, and keeping only
- * the dim_max-skeleton.
- *
- * In order to build this complex, the algorithm first builds the graph.
- * The filtration value of each edge is computed from a user-given distance
- * function, or directly read from the distance matrix.
- * In a second step, this graph is inserted in a simplicial complex, which then
- * gets expanded to a flag complex.
- * 
- * The input can be given as a range of points and a distance function, or as a
- * distance matrix.
- * 
- * Vertex name correspond to the index of the point in the given range (aka. the point cloud).
- * 
- * \image html "rips_complex_representation.png" "Rips-complex one skeleton graph representation"
- * 
- * On this example, as edges (4,5), (4,6) and (5,6) are in the complex, simplex (4,5,6) is added with the filtration
- * value set with \f$max(filtration(4,5), filtration(4,6), filtration(5,6))\f$.
- * And so on for simplex (0,1,2,3).
- * 
- * If the Rips_complex interfaces are not detailed enough for your need, please refer to
- * <a href="_persistent_cohomology_2rips_persistence_step_by_step_8cpp-example.html">
- * rips_persistence_step_by_step.cpp</a> example, where the constructions of the graph and
- * the Simplex_tree are more detailed.
- *
- * \section sparserips Sparse Rips complex
- *
- * Even truncated in filtration value and dimension, the Rips complex remains
- * quite large. However, it is possible to approximate it by a much smaller
- * filtered simplicial complex (linear size, with constants that depend on
- * &epsilon; and the doubling dimension of the space) that is
- * \f$(1+O(\epsilon))-\f$interleaved with it (in particular, their persistence
- * diagrams are at log-bottleneck distance at most \f$O(\epsilon)\f$).
- *
- * The sparse Rips filtration was introduced by Don Sheehy
- * \cite sheehy13linear. We are using the version described in
- * \cite buchet16efficient (except that we multiply all filtration values
- * by 2, to match the usual Rips complex), which proves a
- * \f$\frac{1+\epsilon}{1-\epsilon}\f$-interleaving, although in practice the
- * error is usually smaller.
- * A more intuitive presentation of the idea is available in
- * \cite cavanna15geometric, and in a video \cite cavanna15visualizing.
- *
- * The interface of `Sparse_rips_complex` is similar to the one for the usual
- * `Rips_complex`, except that one has to specify the approximation factor, and
- * there is no option to limit the maximum filtration value (the way the
- * approximation is done means that larger filtration values are much cheaper
- * to handle than low filtration values, so the gain would be too small).
- *
- * Theoretical guarantees are only available for \f$\epsilon<1\f$. The
- * construction accepts larger values of &epsilon;, and the size of the complex
- * keeps decreasing, but there is no guarantee on the quality of the result.
- *
- * \section ripspointsdistance Point cloud and distance function

- * 
- * Analogously to the case of distance matrix, Rips complexes can be also constructed based on correlation matrix. 
- * Given a correlation matrix M, comportment-wise 1-M is a distance matrix.
- * This example builds the one skeleton graph from the given corelation matrix and threshold value.

- * Then, it is asked to display information about the simplicial complex.
- * 
- * \include Rips_complex/example_one_skeleton_rips_from_correlation_matrix.cpp
- * 
- * When launching:
- * 
- * \code $> ./example_one_skeleton_from_correlation_matrix
- * \endcode
- *
- * the program output is:
- * 
- * \include Rips_complex/one_skeleton_rips_from_correlation_matrix_for_doc.txt
- * 
- * All the other constructions discussed for Rips complex for distance matrix can be also performed for Rips complexes
- * construction from correlation matrices.
- * 
- * @warning As persistence diagrams points will be under the diagonal, bottleneck distance and persistence graphical
- * tool will not work properly, this is a known issue.

- * @{
- * \author    Cl&eacute;ment Maria
- *
- * A simplicial complex \f$\mathbf{K}\f$ on a set of vertices \f$V = \{1, \cdots ,|V|\}\f$ is a collection of
- * simplices \f$\{\sigma\}\f$, \f$\sigma \subseteq V\f$ such that
- * \f$\tau \subseteq \sigma \in \mathbf{K} \rightarrow \tau \in \mathbf{K}\f$. The dimension \f$n=|\sigma|-1\f$ of
- * \f$\sigma\f$ is its number of elements minus \f$1\f$.
- *
- * A filtration of a simplicial complex is a function \f$f:\mathbf{K} \rightarrow \mathbb{R}\f$ satisfying
- * \f$f(\tau)\leq f(\sigma)\f$ whenever \f$\tau \subseteq \sigma\f$. Ordering the simplices by increasing filtration
- * values (breaking ties so as a simplex appears after its subsimplices of same filtration value) provides an
- * indexing scheme.
- *
- * \section filteredcomplexesimplementation Implementations
- * \subsection filteredcomplexessimplextree Simplex tree
- * There are two implementation of complexes. The first on is the Simplex_tree data structure. The simplex tree is an
- * efficient and flexible data structure for representing general (filtered) simplicial complexes. The data structure
- * is described in \cite boissonnatmariasimplextreealgorithmica
- * \image html "Simplex_tree_representation.png" "Simplex tree representation"
- * 
- * \subsubsection filteredcomplexessimplextreeexamples Examples
- * 
- * Here is a list of simplex tree examples :
- * \li <a href="_simplex_tree_2simple_simplex_tree_8cpp-example.html">
- * Simplex_tree/simple_simplex_tree.cpp</a> - Simple simplex tree construction and basic function use.
- *
- * \li <a href="_simplex_tree_2simplex_tree_from_cliques_of_graph_8cpp-example.html">
- * Simplex_tree/simplex_tree_from_cliques_of_graph.cpp</a> - Simplex tree construction from cliques of graph read in
- * a file.
- * 
- * Simplex tree construction with \f$\mathbb{Z}/3\mathbb{Z}\f$ coefficients on weighted graph Klein bottle file:
- * \code $> ./simplex_tree_from_cliques_of_graph ../../data/points/Klein_bottle_complex.txt 3 \endcode
- * \code Insert the 1-skeleton in the simplex tree in 0.000404 s. 
-max_dim = 3
-Expand the simplex tree in 3.8e-05 s. 
-Information of the Simplex Tree: 
-Number of vertices = 10   Number of simplices = 98 \endcode
- * 
- * \li <a href="_simplex_tree_2example_alpha_shapes_3_simplex_tree_from_off_file_8cpp-example.html">
- * Simplex_tree/example_alpha_shapes_3_simplex_tree_from_off_file.cpp</a> - Simplex tree is computed and displayed
- * from a 3D alpha complex (Requires CGAL, GMP and GMPXX to be installed).
- * 
- * \li <a href="_simplex_tree_2graph_expansion_with_blocker_8cpp-example.html">
- * Simplex_tree/graph_expansion_with_blocker.cpp</a> - Simple simplex tree construction from a one-skeleton graph with
- * a simple blocker expansion method.
- *
- * \subsection filteredcomplexeshassecomplex Hasse complex
- * The second one is the Hasse_complex. The Hasse complex is a data structure representing explicitly all co-dimension
- * 1 incidence relations in a complex. It is consequently faster when accessing the boundary of a simplex, but is less
- * compact and harder to construct from scratch.

- * 
- * This Gudhi component is a wrapper around 
- * <a target="_blank" href="http://doc.cgal.org/latest/Spatial_searching/index.html">CGAL dD spatial searching algorithms</a>.
- * It provides a simplified API to perform (approximate) neighbor searches. Contrary to CGAL default behavior, the tree
- * does not store the points themselves, but stores indices.
- *
- * For more details about the data structure or the algorithms, or for more advanced usages, reading 
- * <a target="_blank" href="http://doc.cgal.org/latest/Spatial_searching/index.html">CGAL documentation</a>
- * is highly recommended.
- * 
- * \section spatial_searching_examples Example
- * 
- * This example generates 500 random points, then performs all-near-neighbors searches, and queries for nearest and furthest neighbors using different methods.

-\section tangentialdefinition Definition
-
-A Tangential Delaunay complex is a <a target="_blank" href="https://en.wikipedia.org/wiki/Simplicial_complex">simplicial complex</a>
-designed to reconstruct a \f$k\f$-dimensional smooth manifold embedded in \f$d\f$-dimensional Euclidean space. 
-The input is a point sample coming from an unknown manifold, which means that the points lie close to a structure of "small" intrinsic dimension.
-The running time depends only linearly on the extrinsic dimension \f$ d \f$
-and exponentially on the intrinsic dimension \f$ k \f$.
-
-An extensive description of the Tangential complex can be found in \cite tangentialcomplex2014.
-
-\subsection whatisthetc What is a Tangential Complex?
-
-Let us start with the description of the Tangential complex of a simple example, with \f$ k=1 \f$ and \f$ d=2 \f$.
-The input data is 4 points \f$ P \f$ located on a curve embedded in 2D.
-\image html "tc_example_01.png" "The input"
-For each point \f$ p \f$, estimate its tangent subspace \f$ T_p \f$ (e.g. using PCA).
-\image html "tc_example_02.png" "The estimated normals"
-Let us add the Voronoi diagram of the points in orange. For each point \f$ p \f$, construct its star in the Delaunay triangulation of \f$ P \f$ restricted to \f$ T_p \f$.
-\image html "tc_example_03.png" "The Voronoi diagram"
-The Tangential Delaunay complex is the union of those stars.
-
-In practice, neither the ambient Voronoi diagram nor the ambient Delaunay triangulation is computed.
-Instead, local \f$ k \f$-dimensional regular triangulations are computed with a limited number of points as we only need the star of each point.
-More details can be found in \cite tangentialcomplex2014.
-
-\subsection inconsistencies Inconsistencies
-
-Inconsistencies between the stars can occur.
-An inconsistency occurs when a simplex is not in the star of all its vertices.
-
-Let us take the same example.
-\image html "tc_example_07_before.png" "Before"
-Let us slightly move the tangent subspace \f$ T_q \f$
-\image html "tc_example_07_after.png" "After"
-Now, the star of \f$ Q \f$ contains \f$ QP \f$, but the star of \f$ P \f$ does not contain \f$ QP \f$. We have an inconsistency.
-\image html "tc_example_08.png" "After"
-
-One way to solve inconsistencies is to randomly perturb the positions of the points involved in an inconsistency.
-In the current implementation, this perturbation is done in the tangent subspace of each point. 
-The maximum perturbation radius is given as a parameter to the constructor.
-
-In most cases, we recommend to provide a point set where the minimum distance between any two points
-is not too small. This can be achieved using the functions provided by the Subsampling module. Then, a good value to start with for
-the maximum perturbation radius would be around half the minimum distance between any two points. 
-The \ref example_with_perturb below shows an example of such a process.
-
-In most cases, this process is able to dramatically reduce the number of inconsistencies, but is not guaranteed to succeed.
-
-\subsection output Output
-
-The result of the computation is exported as a `Simplex_tree`. It is the union of the stars of all the input points.
-A vertex in the Simplex Tree is the index of the point in the range provided by the user. 
-The point corresponding to a vertex can also be obtained through the `Tangential_complex::get_point` function.
-Note that even if the positions of the points are perturbed, their original positions are kept (e.g. `Tangential_complex::get_point` returns the original position of the point).
-
-The result can be obtained after the computation of the Tangential complex itself and/or after the perturbation process.
-
-\section simple_example Simple example
-
-This example builds the Tangential complex of point set.
-Note that the dimension of the kernel here is dynamic, which is slower, but more flexible:
-the intrinsic and ambient dimensions does not have to be known at compile-time.
-
-\include Tangential_complex/example_basic.cpp
-
-\section example_with_perturb Example with perturbation
-
-This example builds the Tangential complex of a point set, then tries to solve inconsistencies
-by perturbing the positions of points involved in inconsistent simplices.
-Note that the dimension of the kernel here is static, which is the best choice when the
-dimensions are known at compile-time.

-   \section witnessdefinitions Definitions
-
-   Witness complex is a simplicial complex defined on two sets of points in \f$\mathbb{R}^D\f$:
-
-   \li \f$W\f$ set of **witnesses** and 
-   \li \f$L\f$ set of **landmarks**.
-
-   Even though often the set of landmarks \f$L\f$ is a subset of the set of witnesses \f$ W\f$, it is not a requirement for the current implementation.
-
-   Landmarks are the vertices of the simplicial complex
-   and witnesses help to decide on which simplices are inserted via a predicate "is witnessed".
-
-   De Silva and Carlsson in their paper \cite de2004topological differentiate **weak witnessing** and **strong witnessing**:
-
-   - *weak*:   \f$ \sigma \subset L \f$ is witnessed by \f$ w \in W\f$ if \f$ \forall l \in \sigma,\ \forall l' \in \mathbf{L \setminus \sigma},\ d(w,l) \leq d(w,l') \f$
-   - *strong*: \f$ \sigma \subset L \f$ is witnessed by \f$ w \in W\f$ if \f$ \forall l \in \sigma,\ \forall l' \in \mathbf{L},\ d(w,l) \leq d(w,l') \f$
-
-   where \f$ d(.,.) \f$ is a distance function.
-
-   Both definitions can be relaxed by a real value \f$\alpha\f$:
-
-   - *weak*:   \f$ \sigma \subset L \f$ is \f$\alpha\f$-witnessed by \f$ w \in W\f$ if \f$ \forall l \in \sigma,\ \forall l' \in \mathbf{L \setminus \sigma},\ d(w,l)^2 \leq d(w,l')^2 + \alpha^2 \f$
-   - *strong*: \f$ \sigma \subset L \f$ is \f$\alpha\f$-witnessed by \f$ w \in W\f$ if \f$ \forall l \in \sigma,\ \forall l' \in \mathbf{L},\ d(w,l)^2 \leq d(w,l')^2 + \alpha^2 \f$
-
-   which leads to definitions of **weak relaxed witness complex** (or just relaxed witness complex for short) and **strong relaxed witness complex** respectively.
-
-   \image html "swit.svg" "Strongly witnessed simplex"
-
-   In particular case of 0-relaxation, weak complex corresponds to **witness complex** introduced in \cite de2004topological, whereas 0-relaxed strong witness complex consists of just vertices and is not very interesting.
-   Hence for small relaxation weak version is preferable.
-   However, to capture the homotopy type (for example using Gudhi::persistent_cohomology::Persistent_cohomology) it is often necessary to work with higher filtration values. In this case strong relaxed witness complex is faster to compute and offers similar results.
-
-   \section witnessimplementation Implementation
-   
-   The two complexes described above are implemented in the corresponding classes 
-   - Gudhi::witness_complex::Witness_complex
-   - Gudhi::witness_complex::Euclidean_witness_complex
-   - Gudhi::witness_complex::Strong_witness_complex
-   - Gudhi::witness_complex::Euclidean_strong_witness_complex
-
-   The construction of the Euclidean versions of complexes follow the same scheme:
-   1. Construct a search tree on landmarks (for that Gudhi::spatial_searching::Kd_tree_search is used internally).
-   2. Construct lists of nearest landmarks for each witness (special structure Gudhi::witness_complex::Active_witness is used internally).
-   3. Construct the witness complex for nearest landmark lists.
-
-   In the non-Euclidean classes, the lists of nearest landmarks are supposed to be given as input.
-
-   The constructors take on the steps 1 and 2, while the function 'create_complex' executes the step 3.
-
-   \section witnessexample1 Example 1: Constructing weak relaxed witness complex from an off file
-
-   Let's start with a simple example, which reads an off point file and computes a weak witness complex.

-  Point_vector point_vector, landmarks;
-  Gudhi::Points_off_reader<Point_d> off_reader(file_name);
-  point_vector = Point_vector(off_reader.get_point_cloud());

-/*! \page fileformats File formats
-
- \tableofcontents
-
- \section FileFormatsPers Persistence Diagram
-
- Such a file, whose extension is usually `.pers`, contains a list of persistence intervals.<br>
- Lines starting with `#` are ignored (comments).<br>
- Other lines might contain 2, 3 or 4 values (the number of values on each line must be the same for all lines):
- \verbatim
-   [[field] dimension] birth death
- \endverbatim
-
- Here is a simple sample file:
- \verbatim
-   # Persistence diagram example
-   2 2.7 3.7
-   2 9.6 14.
-   # Some comments
-   3 34.2 34.974
-   4 3. inf
- \endverbatim
-
- Other sample files can be found in the `data/persistence_diagram` folder.
-
- Such files can be generated with `Gudhi::persistent_cohomology::Persistent_cohomology::output_diagram()` and read with
- `Gudhi::read_persistence_intervals_and_dimension()`, `Gudhi::read_persistence_intervals_grouped_by_dimension()` or
- `Gudhi::read_persistence_intervals_in_dimension()`.
- 
-
- \section FileFormatsIsoCuboid Iso-cuboid
-
- Such a file describes an iso-oriented cuboid with diagonal opposite vertices (min_x, min_y, min_z,...) and (max_x, max_y, max_z, ...). The format is:<br>
- \verbatim
-   min_x min_y [min_z ...]
-   max_x max_y [max_z ...]
- \endverbatim
-
- Here is a simple sample file in the 3D case:
- \verbatim
-   -1. -1. -1.
-   1. 1. 1.
- \endverbatim
-
-
- \section FileFormatsPerseus Perseus
-
- This file format is the format used by the Perseus software
- (http://www.sas.upenn.edu/~vnanda/perseus/) by Vidit Nanda.
- The first line contains a number d begin the dimension of the
- bitmap (2 in the example below). Next d lines are the numbers of top dimensional cubes in each dimensions (3 and 3
- in the example below). Next, in lexicographical order, the filtration of top dimensional cubes is given (1 4 6 8
- 20 4 7 6 5 in the example below).
- 
- \image html "exampleBitmap.png" "Example of a input data."
- 
- The input file for the following complex is:
- \verbatim
- 2
- 3
- 3
- 1
- 4
- 6
- 8
- 20
- 4
- 7
- 6
- 5
- \endverbatim
-
- To indicate periodic boundary conditions in a
- given direction, then number of top dimensional cells in this direction have to be multiplied by -1. For instance:
-
- \verbatim
- 2
- -3
- 3
- 1
- 4
- 6
- 8
- 20
- 4
- 7
- 6
- 5
- \endverbatim
-
- Indicate that we have imposed periodic boundary conditions in the direction x, but not in the direction y.
-
- Other sample files can be found in the `data/bitmap` folder.

- * \section Introduction Introduction
- * The GUDHI library (Geometry Understanding in Higher Dimensions) is a generic open source
- * <a class="el" target="_blank" href="http://gudhi.gforge.inria.fr/doc/latest/">C++ library</a> for
- * Computational Topology and Topological Data Analysis
- * (<a class="el" target="_blank" href="https://en.wikipedia.org/wiki/Topological_data_analysis">TDA</a>).
- * The GUDHI library intends  to help the development of new algorithmic solutions in TDA and their transfer to
- * applications. It provides robust, efficient, flexible and easy to use implementations of state-of-the-art
- * algorithms and data structures.
- * 
- * The current release of the GUDHI library includes:
- * 
- * \li Data structures to represent, construct and manipulate simplicial complexes.
- * \li Simplification of simplicial complexes by edge contraction.
- * \li Algorithms to compute persistent homology and bottleneck distance.
- * 
- * All data-structures are generic and several of their aspects can be parameterized via template classes.
- * We refer to \cite gudhilibrary_ICMS14 for a detailed description of the design of the library.

-    The Skeleton-Blocker data-structure proposes a light encoding for simplicial complexes by storing only an *implicit*
-    representation of its simplices \cite socg_blockers_2011,\cite blockers2012. Intuitively, it just stores the
-    1-skeleton of a simplicial complex with a graph and the set of its "missing faces" that is very small in practice.
-    This data-structure handles all simplicial complexes operations such as simplex enumeration or simplex removal but
-    operations that are particularly efficient are operations that do not require simplex enumeration such as edge
-    iteration, link computation or simplex contraction.<br>
