MATLAB speeding up open command

I used profile to check my code for speeding up 90% of my code is going on for

open('filename.mat')

I am looking for ways to speed it up all the files are .mat with around 40K lines on 13 columns I was wondering if you know a way to speed it up, maybe changing it to

load('filename.mat')

Is there a speed difference between them?

open has to determine the file type - if it determines it to be a .mat file it will call load.

I wouldn't have expected it to take very long to do that though...

Are you loading files over a network?

Are you running out of RAM?

To answer your question I would expect changing to load to speed things up but not by a lot... Try it and see! :)
