Distance Hadamard produces spectra of splits from a distance matrix.

Usage

distanceHadamard(dm, eps = 0.001)

Arguments

dm

A distance matrix.

eps

Threshold value for splits.

Value

distanceHadamard returns a matrix. The first column contains the distance spectra, the second one the edge-spectra. If eps is positive an object of with all splits greater eps is returned.
