octave_distance, an Octave code which estimates the typical distance between a pair of points randomly selected from the surface or interior of a geometric object such as a circle, disk, sphere, cube.

- annulus_distance_histogram.m, displays a histogram from N samples of pairwise distances.
- annulus_distance_stats.m, estimates the mean and variance of the pairwise distance, using sampling.
- ellipse_sample.m, returns N random points in a given annulus.
