cloud_variance_test: Test decomposition of cloud variance.

In corybrunson/cloud: Geometric operations on point clouds

Description

This function verifies that the variance of a cloud is the sum of its variance in the direction of any subspace and the variance of the residual cloud with respect to that subspace.

Usage

cloud_variance_test(cloud, weights, subspace, ...)

Arguments

cloud	An m-by-n matrix of coordinates for m points in n-dimensional space.
weights	An m-element vector of point masses (weights).
subspace	An k-by-n matrix of coordinates spanning the k-dimensional linear subspace or (k - 1)-dimensional affine subspace.
...	Additional arguments passed to cloud_decomposition.
