A1_10 = repmat(A,[1,1,10]);
t = ones(size(A));
for j1 = 1:size(A1_10,3)
p = t;
p(randi(n,600,1)) = 0;

The code set some random elements to zero. If you want to omit randi, what should be done instead?
If you want to get the same result for each run, initialize the randon number generator, see help rand or doc randi - the exact proceeding depends on the Matlab release.
