Let’s say R is a mxn random matrix. How can generate R with each entry of R is independent and identically chosen from any distribution with mean zero and variance mu^2?

You probably want ‘randn’, which chooses entries from a Gaussian distribution with norm 1. To get a variance of mu^2, use
For instance:
I get:
