loadexcept

 function f = loadexcept(file,vars,mode)

 <file> is a string referring to a .mat file
 <vars> is a variable name or a cell vector of variable names to NOT load
 <mode> (optional) is
   0 means load <file> into the base workspace (as well as into struct <f>)
   1 means load <file> into struct <f>
   Default: 0.

 load <file>, excluding variables named by <vars>.

 example:
 x = 1; y = 2;
 save('temp.mat','x','y');
 clear x y;
 loadexcept('temp.mat','x')
 ~exist('x','var')
 exist('y','var')
