Cubical Persistet Homology via coreductions and inclusion maps
cubPers is my implementation of the
Coreduction Homology Algorithm for persistence via inclusion maps
for filtrations of full cubical sets in dimensions 2 and 3.
The algorithm is also available as a part of the
CAPD software library.
Download
To use it you have to download source code,
unpack it to a directory of your choice, go to the make subfolder
and issue
make all
command for Linux environment or
make target=win all
for MS Windows environment. This compiles the package. The executable is then
in bin subfolder.
Usage
The usage is
cubPersMDZ2 filename
where filename denotes the name of a file containing a cubical filtration
in the following format:
dim
size1
size2
[size3]
v1
v2
...
vn
Here dim in the first line of the file stands for the dimension,
which must be 2 or 3. The next lines contain size1, size2 (and size3 when dim-3),
i.e. the sizes of the big cube enclosing the filtration.
This is followed by size1*size2[*size3] lines, each containing the level
of the particular cube on which it joins the filtration.
