Add Laplacian noise to 1D data

White gaussian noise can be added using the below function

out = awgn(in,snr)

Is there a function that can add Laplacian noise? Is it using this randl function?

I suggest you to look in this thread:

BTW, which randl function you're talking about?

Hi,

I understand that you are searching for a function that can add Laplacian noise to 1D data.

R = randl(N) returns an N-by-N matrix containing pseudorandom values drawn from the Laplacian distribution. randl(M, N) or randl([M,N]) returns an M-by-N matrix.

To add Laplacian noise to your data you can use this randl function.
