Just use

   x=randn(m,n);
   y=A*x+B;

and choose A and B appropriate to the sigma, mu that you want.

@Matt J: I think you mean

x = randn(m,n);

[Matt J]

Yep, thanks Roger.

thanks ,excuse me can I write randn 's code just by using rand too?

[Matt J]

I can't see how you would do that, except by using a Central Limit Theorem approximation.
