Common reasons for "index exceeds matrix dimension" error?

Hi everyone,

This is more of a concern than a question, actually. Apologies in advance if this is not appropriate here.

I'm running a particular program and the input is basically a couple hundred txt files. When I first ran the program, it executed everything as desired (more or less). I have changed the input and it worked properly as well.

However, after a couple of turns, I'm running the same program with the input that I used initially and matlab gives an, index exceeds matrix dimension error. I also have cleared the workspace as well.

Are there any possible ideas off the top of your heads for this to happen? Or threads/Documentations that I can refer?

Again, this is only a concern and thus I haven't provided any code or any details. I'm wondering about possible or, maybe, common reasons.

I'd apologize if this wasted your time or something :)

Is it possible that you have overwritten files or maybe some of them are now empty?

Good point. I replaced the input files when I was trying out different sets of inputs. But I was using the same set of files(inputs) which I used initially.

Thank you. I will try starting over with newer files as well.
