Return a cell array of all MATLAB keywords
It would be better if the solution didn't contain the answer. Also, in the problem statement you should probably specify that the keywords must be sorted alphabetically (and appear only once each). Otherwise a cell array such as {'if', 'for', 'else', ...} would satisfy the problem statement, but fail the Test Suite — as demonstrated in Solution 1329165.
