Might be a good idea to change the test suite to "assert(isequal(cube3(),cube3().^3))" so that the answer isn't revealed by looking at the test suite.

Michael C. had a good point, but you also need "assert(numel(unique(cube3()))==3)"

Yo may need to check for length 3

Add a test to assert that length == 3.

It would be a good idea to check that a length 3 vector is returned.
