Please do not check for the occurance of "for" in general, because "UniFORmOutput" has nothing to do with looping ;-)

Your predefined function signature has only one parameter, altough two were submitted. Same problem without the "for" restriction: http://www.mathworks.com/matlabcentral/cody/problems/555-low-high-low-high-turn-around-create-a-subindices-vector

This is an excellent problem.

I agree with Dirk. Change your regexp to check for instances of eval, for, and while that are not preceded or followed by additional letters.

give me a hint, should we use a specific function here?

Tip: replace UniformOutput with uni.

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.

A separate test case that tests for functions that are against the rules would improve this problem. In this case, the "for" in "UniformOutput" was getting caught by the search. A separate test case would have made clear that the solution functions properly but contains an outlawed string.

'Uniformoutput' is now valid, while as for OP's rules for loop is still not allowed.

Why x3=[] in the test ?
Nice recursion !
