Draw random variables student t distribution

I want to draw standardized values with a t-distribution, so I want to generate iid numbers from the student-t distribution with mean zero and variance 1.

I can use the Matlab function 'trnd(nu).' Does this generate random numbers with mean zero and variance 1?

In particular, no you can't get a variance of 1.
