Covering some basic topics I haven't seen elsewhere on Cody.
Return an array of the benchmark values for MATLAB.
The test suite already spoils the solution.
True. In general that should be avoided, although admittedly it's difficult here because if the correct answer were hard-coded, then changes to: (i) the hardware on which Cody runs; or (ii) the version of MATLAB that Cody employs may eventually invalidate it. Having said that, the Test Suite could still be tightened up (see e.g. Solution 1461085).
