I think the test suite is broken, I appear to only get x = [21,6;35,10] as the input and y is being displayed as a vector instead of the matrix that is returned. So either the return is being compared to an x that was not sent or y being a vector is causing the test cases to always fail.
Andrew, I just tried resubmitting my original solution, and the test suite was OK. What is the exact problem that you're having with the test suite when you submit your solution?
Test suite compares y to itself--should compare y to x.
Hah! Great catch. It's fixed now, but you still get a like for being so sneaky...
