NAME

ripser-coeff - fast computation of persistent homology of flag complexes

SYNOPSIS

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

DESCRIPTION

ripser-coeff 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. Unlike ripser, it computes over an arbitrary finite field.

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