    _______________________________________________________

Details:

The wishrnd function takes two arguments (optionally four) - the correlation
matrix Sigma and the degrees of freedom. The function creates an error if less
than three inputs are given.

To generate the error:

A = rand(3,3);
Sigma = A*A';
n=1;
wishrnd(Sigma, n)


The above should generate a single wishart sample.
