Abstract

cvxhull identifies points defining the convex hulls of a group of points in two-dimensional space. Each hull is defined by two lines joining the bottom-left point to the top-right point. The data are sorted within the routine but sortpreserve returns the data to their original order after the call, whether or not it was completed. The routine may be called repeatedly to calculate a variety of hulls. The routines provide a complete replacement for gr16 (STB-23).
