surfarb.m

surf() is a great visualization tool, but it requires x and y coordinates to be gridded. If collecting x, y, and z data from an experiment, you often wind up with a random collection of x-y points, which cannot be plotted using surf. surfarb uses delaunay triangulation to generate a surface from an arbitrary collection of points, and can be used as a drop-in replacement for surf for these kinds of data sets.
