convhulln (MATLAB Function Reference)

n-D convex hull

Syntax

K = convhulln(X)

Description

K = convhulln(X) returns the indices K of the points in X that comprise the facets of the convex hull of X. X is an m-by-n array representing m points in n-D space. If the convex hull has p facets then K is p-by-n+1.

Note convhulln is based on qhull [1]. For information about qhull, see http://www.geom.umn.edu/software/qhull/. For copyright information, see http://www.geom.umn.edu/software/download/COPYING.html.
