JD, I think I figured out why Binbin and I (and more than likely a good number of other players) are having issues with your test suite. I think your "assert(isempty(strfind(filetext, '0')),'0 forbidden')" line is catching everyone who has the digit 0 in their MATLAB ID number. Binbin and I have that, while you do not. I just hacked the test suite, and tried a non-hacking correct answer from Alfonso...with the same result - my solution failed because 0 is forbidden.
this is still true while the only diff is this is a badge problem now . Please fix
The offending line—asserting lack of '0'—has been commented out.
Thanks goc :)

I'm also curious about the test suite, Binbin. I'm not quite sure why
y = diff([x+1 1]); fails the test suite.
Binbin, James - I am not sure why either of your solutions didn't work. I submitted them, and they both passed... Maybe try resubmitting...? Maybe there's a bug in Cody...?

why this solution is wrong?
Sorry for the double comment, but I can't delete the one I posted under my solution.
I'm also curious about the test suite, Binbin. I'm not quite sure why my solution of "y = diff([x+1 1]);" fails the first test suite. I don't see any of the forbidden words in there.
