noise = [ zeros(N,1) ; rand(M,1) ];
distorted = source + noise;

you need to specify the values of M and N. For example, if you want to add noise to the first 10 points of your signal you can use,
N=10
M=numel(t)
changing the values of M and N will enable you to choose the signal indexes where the noise is applied
