Additional test cases have been added.
Dear @bmtran, how can does work? I ask this because you add the vector diag(M) to a matrix. I think you should write
diag(diag(M)) instead of diag(M). Am I wrong?
it should be fairly easy to diagnose what i'm doing if you run each argument of my code separately in MATLAB and look at what it's doing, but I don't wanna give anything away to people who have yet to solve this problem.
