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
