They are switched on by defining t Furthermore, one of the following options needs to be chosen to specify the format for the input files: - - `FILE_FORMAT_LOWER_TRIANGULAR_CSV`: lower triangular distance matrix; a comma (or whitespace, or other non-numerical character) separated list of the distance matrix entries below the diagonal, sorted lexicographically by row index, then column index - - `FILE_FORMAT_UPPER_TRIANGULAR_CSV`: upper triangular distance matrix; similar to the previous, but for the entries above the diagonal; suitable for output from the MATLAB function `pdist`, saved in a CSV file + - `FILE_FORMAT_LOWER_DISTANCE_MATRIX`: lower triangular distance matrix; a comma (or whitespace, or other non-numerical character) separated list of the distance matrix entries below the diagonal, sorted lexicographically by row index, then column index + - `FILE_FORMAT_UPPER_DISTANCE_MATRIX`: upper triangular distance matrix; similar to the previous, but for the entries above the diagonal; suitable for output from the MATLAB function `pdist`, saved in a CSV file + - `FILE_FORMAT_DISTANCE_MATRIX`: full distance matrix; similar to the above, but for all entries of the distance matrix - `FILE_FORMAT_DIPHA`: DIPHA distance matrix as described on the [DIPHA] website - `FILE_FORMAT_POINT_CLOUD`: point cloud; a comma (or whitespace, or other non-numerical character) separated list of coordinates of the points in some Euclidean space, one point per line For example, to build with support for coefficients: ```sh -$ c++ -std=c++11 ripser.cpp -o ripser -Ofast -D NDEBUG -D FILE_FORMAT_LOWER_TRIANGULAR_CSV -D USE_COEFFICIENTS +$ c++ -std=c++11 ripser.cpp -o ripser -Ofast -D NDEBUG -D FILE_FORMAT_LOWER_DISTANCE_MATRIX -D USE_COEFFICIENTS ``` -A Makefile is provided with some variants of the above options.
