How to generate data with a specific distribution

Matlab provides random number generating from a uniform distribution (rand). Is there a way to generate data from other distributions that Matlab supports like Chi-Square??

Use the random function. Here's an example of creating a 10x3 matrix of random numbers using a Chi-Square distribution with 2 degrees of freedom:

y = random('chi2',2,10,3)

If you have the stats toolbox with random you can chose from a set of distributions.

Otherwise to get a chi-squared just generate standard normals and sum their squares: http://en.wikipedia.org/wiki/Chi-square_distribution
