You should make the timing test dynamic. The current optimally vectorized solution is about 7 or 8 times faster than the default looped solution. You could add a test that confirms at least a 75% time reduction.

The linspace function is for when you know how many elements you want, the colon operator is for when you know the step size.

Riksubmitted a评论toProblem 801. Construct an index vector from two input vectors in vectorized fashion

Actually arrayfun should also be outlawed, as that simply hides the loop at a performance cost. I haven't seen a vectorized solution yet, only recursions and implicit loops (and the usual cheat-submissions). If you want a more robust cheat-detection you should have a separate test which runs as first test. That one should not call the submission to avoid it overwriting functions like fileread and assert.
