I'm trying to query variable names in a very large .mat
file (> 1 GB) without having to load the .mat file first
(which takes 10+ minutes). I'm running Matlab 7.0 SP2 on
32-bit Windows XP Professional.
I thought I had hit the jackpot with:
vars = whos('-file','largefile.mat')
But this still takes what I consider to be an excessive
amount of time (3-5 minutes).
Are there any other ideas about how to return the variable
names in a very large .mat file in a timely manner?

Considering the huge file size, it will take some time to search the variables. Other option is you open the workspace and load the file directly there and see the variables in the works space.

Right click on the .mat file in the Current Directory window and
select "Import Data". Is that any faster?

If you choose the way "Import Data", you can use the function
uiimport
