Hi everyone,
I have a question to ask on this forum. I want to create random variables from the correlation matrix, found from the PSD function.
How can I proceed,
Thank you.

Random variables from WHAT distribution? (Sort of a trick question. Anything but a normal distribution will be somewhat difficult.)

Here is an example
sigma = [1 0.2;0.2 1];
x = randn(1000,2)*chol(sigma);
corrcoef(x) % verify
