MATLAB Matlab - creating Gaussian noise

Click For Summary
To create a matrix of complex Gaussian noise with unit power and a mean of zero, the approach involves generating two independent real Gaussian matrices. The code snippet provided uses the `randn` function to create two matrices, A and B, filled with normally distributed random numbers. The complex matrix C is then formed by combining A and B, where A represents the real part and B represents the imaginary part, using the formula C = A + j*B. To ensure the matrix has unit power, normalization may be required after generating the complex matrix. This method is effective for defining a test sample for algorithms that require complex noise characteristics.

Does anyone know how to create a matrix of complex Gaussian noise (with unit power = 1 and mean of zero)? I need to define a test sample for my algorithm, but I'm stuck at defining my test bench.

Any help would be appreciated, thanks!
