Hi all!
i have lots of functions which must access to some tables i memorized in a .mat file.
Unfortunately theese tables are becoming bigger and bigger and so the time of the execution of the "load" command is becoming longer and longer...
have you got any suggestions to improve the system?
thanks a lot

a hint:
- scrutinizing perusal of

     help load;
% shall show you a remedy...
% ...as long as you've organized your MAT-file intelligently, of course...

if you do a

     help load;
% then look at line #5 of the output in the command window...
%{
...
         S = LOAD(FILENAME, VARIABLES) ...
...
%}
