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.
Additional test cases have been added.
Running this on octave returns the correct results yet the page still says I'm wrong.
function y = triangMatrix(x)
for i=1:rows(x);
for j=1:columns(x);
if j>i;
x(i,j)=0;
else
endif
endfor
endfor
disp(x)
