.SH NAME
ripser-coeff \- fast computation of persistent homology of flag complexes
.SH SYNOPSIS
.B ripser-coeff
[\fB\-\-help\fR]
[\fB\-\-format\fR \fIformat\fR]
[\fB\-\-dim \fIk\fR]
[\fB\-\-threshold \fIt\fR]
[\fB\-\-ratio \fIr\fR]
[\fB\-\-modulus \fIp\fR]
[\fIfilename\fR]
.SH DESCRIPTION
.B 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 \fBripser\fR, it
computes over an arbitrary finite field.

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