I want to create matrix of 0's and 1's of which 20% of the elements of the matrix is 1's. The following the code I tried. neighbor_matrix = [ones(10,50);zeros(40,50)]; But the out come is not in the way I want. I want the distribution shouldn't be 1's and 0's are in separate manner. Thank you.

>> M = +(rand(50,50)<0.2);
>> mean(M(:)) % testing
ans = 0.19880

neighbor_matrix = [ones(10,50);zeros(40,50)];
neighbor_matrix(:)=neighbor_matrix(randperm(2500));
