I want to generate iid samples which have distribution complex gaussian with some non-zero mean, say, S and variance V which is not unity. Can someone please guide me with this problem?

It doesnt really produce the complex numbers, can you guide me what I am missing here?

It does for me,

mvnrnd(1i*[1;2;3],diag([4,5,6]),10)
