I have two matrices A and xx.. The dimension of the matrix A is 9 x 3 complex double and that of xx is 3 x 500 complex double. The product of A and xx is X1 whose dimesnion is 9 x 500 complex double.
Now I want to generate a noise matrix of the same dimension i.e., 9 x 500 complex double using the command awgn() and add to X1. How can we generate this noise?

I'd use it twice. Once to apply to the real part, and again to apply to the imaginary part.
