I'm trying to figure out a way to search for only part of a filename. I have multiple files that have similar components.

For example:
abc123_5687482
abc124_8914573
abc125_1795362
abc126_7831568

I was wondering if there is a way to have MATLAB do a wildcard search to find if file abc123_5687482 exists by only using abc123 as the search. I've tried using exist() and fopen, but neither one of these seem to recognize wildcard inputs.

Thanks!

Hi Kirsten,
I am having the same sort of problem to solve, my file names finish in _V.dat, _D.dat ect...
I have been trying with regexp,and searching in the folder with ls.
I stay in contact with you if I find an effective way, and please tell me if you manage to do it too.

Bye!

Dear Kirsten,

Do you mean this:
d = dir('abc123*')
?

Good luck, Jan
