10 Sep 2009 RANDRAW Efficient Random Variates Generator (from over 50 distributions). Author: Alex Bar-Guy

Generally very useful. Agree that this ought to be standard in Matlab w/o toolboxes.

However, there seems to be a bug in 'beta'. When I have a=1, b>1 I get a kink in the cdf at x=0.5 and it does not follow betainc as expected.

As soon as I have a>1, even a=1.000001, this kink goes away and the cdf matches betainc perfectly. Any ideas what's going on?
