MATLAB: Generate random binary matrix under a condition

MATLABmatrixrandom

I want to generate a matrix with values that are either zero or one, but the sum of elements in each column is <=1. To generate a random m by n matrix, we use x=randi([0,1],m,n), but what to add to force the sum of elements in each column be <=1…that is only single '1' element in each column.

Best Answer

m = 5;
n = 6;
A = zeros(m,n);
for k = 1:n
    c = randi([0,m]);
    if c > 0
        A(c,k) = 1;
    end
end
