Least sqaures curve fitting and process communication (lst_sqrs.c)

This example creates a Bspline curve that least squares approximates a given set of data points. In the default values, a quadratic Bspline curve of 10 control points least sqaures approximates a set of 100 three dimensional points. Also shown is a polyline of the original (100) points. Arbitrary number of curves will be displayed every, one for every <return> keystroke until Q<return> is typed.
