I have a directory with thousands of files matching a pattern, and all I need is the name of any one of them. If I call dir(pattern), it takes a long time. I'd appreciate any ideas on speeding it up.
Thank you,

About the only possibility that might be faster would be to dir() the entire directory and do the pattern matching yourself. You would get all of the names together, of all of the files.
My expectation would be that doing that would be slower than what you already have, as the pattern matching that exists already is almost certainly more efficient than what you would implement in MATLAB.
