You should first read this:
And then use indexing with just one array (which could be numeric, cell, or struct).

Don't. Automatically generating names for variables (e.g. with eval) is a bad idea. Use cell arrays instead.
Introspective programing (eval and other functions like it) is slow, and the MATLAB documentation warns specifically against it. Using eval is slow, makes debugging difficult, and removes all code helper tools (code checking, syntax hints, code completion, variable highlighting, etc.). A longer discussion can be found here. If you are not an expert and you think you need eval, there are probably better solutions to your problem. Also, if you are not an expert, you might find interesting and helpful hints on this page (and if you are an expert, you can still learn from it).
Edit: Of course I meant variable names, generating filenames is of course not necessarily wrong.
