24 Sep 2007 Random Points in an n-Dimensional Hypersphere Randomly and uniformly distributes points throughout a hypersphere. Author: Roger Stafford Witoelar, Aree

Thanks a lot for the elegant code! I had trouble generating this distribution. Before this, my solution was to sample and reject; but for high dimensions it was too crude and consuming.

Very nice piece of code. I have just two small suggestions for enhancements to the M-file help:

1) Include the calling syntax early in the help. I will admit I sometimes forget the calling syntax for functions I don't use often; my first resort is to type "help <functionname>", either to refresh my memory or to copy and paste the syntax into my code. In a case like this, I can see users perhaps forgetting the order of the parameters.

2) Include an example. Having a example that users can copy and paste included in the help gives people who may not know how to use your function a "known good" state -- from there, they can tweak. For a straightforward function like this, it may not seem necessary, but I think it's a good habit. It could be as simple as the two lines of code to generate the sample image.
