Hi , how can I define a zero-mean gaussian noise with non-unit variance? I know that this command: x= randn(1,100); gives me the normal distribution(zero mean and unit variance), but how to define it for variance equal to f.ex 0.36 ??
tnx a lot...

Multiply the noise by the square root of the desired variance:
sqrt(MyVar) * randn(...)
