compute_betti_curves: Compute Betti curves

In gonzalezgouveia/CosmoBetti: Compute Betti Curves in R

Description

Compute Betti curves of a persistence diagram until a desired dimension, a maximum radius, and output vector lenght. The Betti curve of dimension d of a diagram diag refers to the sequence of Betti numbers of dimension d and diamgram diag along radius from zero to infinity (maximun radius).

Usage

compute_betti_curves(diag, maxdim = -1, maxradius = -1, len = 100)

Arguments

diag	is a persistence diagram from TDA o TDAstats
maxdim	is the maximum dimension the betti curve is computed
maxradius	is the maximum radius the betti curve is computed
len	is the length of each betticurve

Details

if maxdim = -1 then the dimension is infered from diag if maxradius = -1 the maximum radius is infered from diag

Value

A matrix with the Betti curves

Examples

library(TDAstats)
X <- cbind(runif(100), runif(100))
diag <- calculate_homology(X)
compute_betti_curves(diag)
