vac: Variable covariant linear mapping

In corybrunson/cloud: Geometric operations on point clouds

Description

This function encodes a linear mapping that sends a vector in the vector space containing a point cloud $M^J$ to the vector space of variables over $J$, whose coordinates are the covariant coordinates of the cloud, relative to a given point $P$, with respect to the axis generated by the vector.

Usage

vac(cloud, point, dir_vec)

Arguments

cloud	An m-by-n matrix of coordinates for m points in n-dimensional space.
point	An n-coordinate point in the same space as the cloud.
dir_vec	An n-dimensional vector giving the direction of the axis through the cloud.
