Ripser is a persistent homology package for computation of Vietoris-Rips persistence barcodes. Ripser takes in either

• distances matrices (full, lower, or upper) as a CSV
• sparse distances matrices in sparse triplet format
• distance matrices as a binary file (DIPHA or lower triangular)
• point cloud data.

Ripser can also compute representative cocyles for persistent homology.

Ripser also has a Python version, Ripser.py, that also provides visualisation of persistence diagrams and computing lower-star filtrations on images.
