# Bitmap_cubical_complex #

## `cubical_complex_persistence` ##
This program computes persistent homology, by using the Bitmap_cubical_complex class, of cubical complexes provided in text files in Perseus style. See [here](http://gudhi.gforge.inria.fr/doc/latest/fileformats.html#FileFormatsPerseus) for a description of the file format.

Example:

* Create a Cubical Complex from the Perseus style file `CubicalTwoSphere.txt`, computes Persistence cohomology from it and writes the results in a persistence file `CubicalTwoSphere.txt_persistence`:
`cubical_complex_persistence data/bitmap/CubicalTwoSphere.txt`

## `periodic_cubical_complex_persistence` ##

Same as above, but with periodic boundary conditions.

Example:

* Create a Periodical Cubical Complex from the Perseus style file `3d_torus.txt`, computes Persistence cohomology from it and writes the results in a persistence file `3d_torus.txt_persistence`:
`periodic_cubical_complex_persistence data/bitmap/3d_torus.txt`
