That was it. Thanks. I work on m files too much to remember that. Here is a version that is more efficient, and it should actually be more efficient for any matrix because it will only search the required range.

So, now for find(1:50 > 48) instead of going through 1:50 twice, it will only go through 1:50 once and the second time it will only look at 49 and 50.

Hopefully this doesn't introduce any new bugs.
