a=randn(400); generates 400*400 matrix in matlab,
my question is that this function generates different mean and variance matrix at every time when i run the code. so i require fix mean and variance matrix at every time when i run the code. (not a nearest,every time exact and fixed value)

nm=[400,400]
v=0.5; %variance
m=2; % mean
out=m+sqrt(v)*randn(nm)

The error is 1%. What is the desired precision ?
