Covering some basic topics I haven't seen elsewhere on Cody.
Rotate the input matrix 90 degrees counterclockwise (e.g. [1 2; 3 4] -> [2 4; 1 3]
Very nice problem to solve
The test suite does not like the inbuilt function . Says there are too many output arguments!
Is there something wrong with the test suite? The assertion fails and I get the following message:
"Error using rotate Too many output arguments. Error in TestPoint1 (line 3) assert(isequal(rotate(x),y_correct))"
Yes it rotate is an inbuilt MATLAB function and it overshadows this. Changed the function name to rotateBy90

We love vectorized solutions. Problem 1 : remove the row average.
