Covering some basic topics I haven't seen elsewhere on Cody.
Given an input matrix, return a matrix with all elements above and to the right of the main diagonal set to zero. Example:
input = [ 1 1 1 1; 1 1 1 1; 1 1 1 1; 1 1 1 1] output = [1 0 0 0; 1 1 0 0; 1 1 1 0; 1 1 1 1]

Your test suite doesn't really match the problem statement. The tests require matrices with *exactly* all elements abot the main diagonal to be 0 *and* all elements on or below the main diagonal to be 1.
