it's a good question ,you maybe can load the *.mat in a subprogram, then you can return the variable and know which variable is in the *.mat, then use clear to delete them .

Thank you! Is it possible to create a blank mat file? Without loading the varibles in the workspace with it?

The load command should do that automatically. Load open the file, reads the data and closes the file aftwards. So there is no need for your to close it.

In that case use
struct_name = load('foo.mat');
and refer to struct_name.VARIABLENAME instead of VARIABLENAME . Then
clear struct_name
to get rid of them all.

Also there is a button in the top panel, "Clear Workspace".
