When executing one of my functions I'm getting:

Error using reshape To RESHAPE the number of elements must not change.

But my function doesn't even use reshape, any ideas of what is going on here? I mean, what other MATLAB function am I maybe using incorrectly that could be throwing this error?

I didn't change a thing, I have no reason for lying. Maybe the bug was related with the fact that I was using the matlabcontrol java API and calling that MATLAB function a lot during the execution of a genetic algorithm. MATLAB was throwing me that error only sometimes and sometimes it worked fine. After several runs of my Java program the error stopped appearing in MATLAB. I really could not figure out what happened back there. Anyways, thanks a lot for the answers, I'll use the debugger in the future for sure if something goes wrong (even though usually I don't have to because MATLAB points me at the line where the error happened, only this time it wasn't).

I don't think that Jan wanted to suggest that you were lying, but sometimes when we debug code, we check things out by e.g. commenting a few lines at different/random places, and we end up being unable of reproducing the bug when we want to ;-)
