What is the best way to handle huge number of variables when preparing a UI?

Dear All, I coded a UI with MATLAB in which I require a lot of variables from the user. Since during the execution of the UI I need some of them I decided to save all data in *.mat files which are read and written during the execution of the UI. The problem of this implementation is that *.mat can be very big. Thus, I'm thinking about writing variables on file (perhaps binaries) Is there a smart and easy way of achieving this?

The smart and easy way would be to use mat files.
mat files are binary files, and since version seven have been compressed as well:

Why reinvent the wheel ?
If you are worried about the filesize or save / load times, then read these:

PS: the most important thing to remember is to always load into a variable:
S = load(...);
and never load variables directly into the workspace.
