NAME¶

ripser - fast computation of persistent homology of flag complexes

SYNOPSIS¶

ripser [--help] [--format format] [--dim k] [--threshold t] [--ratio r] [filename]

DESCRIPTION¶

ripser computes persistent homology of flag complexes (such as Vietoris-Rips complexes) only, allowing significant gains in computation time and memory usage over the general situation.

See https://arxiv.org/abs/1908.02518 for details.
