Related Julia Packages

This section attempts to provide an overview of Julia packages implementing persistent homology. If you're trying to do something Ripserer is missing, one of these might have what you're looking for.

This list is incomplete and only includes things I'm aware of. The descriptions are based on my (limited) experience with these packages.

• ComputationalHomology.jl uses a different, slower algorithm, but can do some things Ripserer can't such as Čech persistent homology and homology of CW complexes. The package is a part of TDA.jl, which also offers other topological data analysis tools like Mapper.

• Eirene.jl uses a different algorithm based on matroids. A benefit of this algorithm is that it can recover persistent homology generators and a bunch of other data.

• Ripser.jl my deprecated wrapper of the original C++ program. Very bare-bones and outdated. Runs a bit slower than Ripserer.

• Sparips.jl this is a preprocessor that comes with a different wrapper of Ripser. The preprocessor allows you to compute persistent homology of very large datasets. Integrating it with Ripserer is on my TODO list.

• PersistentCohomology.jl does essentially the same thing, but with a different algorithm, that is orders of magnitude slower.

If you are a developer of a persistent homology package not on this list, or any of the information here is incorrect, let me know or open a PR.
