phom.dist: Calculate Distance between Homology Matrices
In TDAstats: Pipeline for Topological Data Analysis

Description Usage Arguments Details Value

Calculates the distance between two matrices containing persistent homology features, usually as returned by the 'calculate_homology' function.

1	phom.dist(phom1, phom2, limit.num = 0)

`phom1`	3-by-n numeric matrix containing persistent homology for first dataset
`phom2`	3-by-n numeric matrix containing persistent homology for second dataset
`limit.num`	limit comparison to only top 'limit.num' features in each dimension

Note that the absolute value of this measure of distance is not meaningful without a null distribution or at least another value for relative comparison (e.g. finding most similar pair within a triplet).

distance vector (1 element per dimension) between 'phom1' and 'phom2'
