Have a look at http://rosebud.sps.queensu.ca/~edd/code/octave-mt.html which implements the much faster Mersenne Twister RNG for Octave and provides Uniform and Standard Normal deviates, just like rand and randn. I found this to be on the order of four times faster than Octave's built-in RNG. -- According to the latest figures, 43% of all statistics are totally worthless. ----------------------------------------------------------------------- Octave is freely available under the terms of the GNU GPL.
