Given a n x n matrix, M, flip its main diagonal.
9 24 1 8 15
23 21 7 14 16
4 6 13 20 22
10 12 19 5 3
11 18 25 2 17
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.
