calcCvxHullFaces: Calculates the convex hull of X

In fmlogcondens: Fast Multivariate Log-Concave Density Estimation

Description

calcCvxHullFaces returns the parameters of the convex hull of X: The indices of points in X that compose the faces of conv(X) (one row per face) as well as the parameters of the hyperplanes that describe these faces.

Usage

calcCvxHullFaces(X)

Arguments

X	Set of data points (one sample per row)

Value

A list consisting of parameters describing the convex hull of X:

cvh	A matrix of indices where each row constitutes one face
ACVH	A matrix where each row constitutes the normal vector of a face
bCVH	A vector where each entry constitutes the offset of the hyperplane for a face
