Confused by test 6, x = [1:3;4:6;7:9;10:12]';
y_correct = [1 6 11]; I think this should be [1 5 9] as array is [1 4 7 10;2 5 8 11;3 6 9 12]
Right solution to right problem
Test #5 is incorrect. Transpose on x makes the diagonal [1 5 9], [1 6 11] are not on any diagonal. #5 is the transpose of #4 and taking the transpose does not change the diagonal, unless you have some other definition for diagonal. A good solution is x(find(eye(size(x))))
