Why do you need to do the second method if the first works? Also the
'-force' option isn't needed in the latest version of Octave for 
reasons of compatibility. Here is my example code that works perfectly

file = 'test.mat';
a = rand(3,3);
if exist('OCTAVE_VERSION')
  save('-mat-binary',file,'a');
else
  save('-mat',file,'a');
end
clear a;
if exist(file, 'file')
  load(file,'a');
end

Note that octave can't save in matlab ascii format (though it can read
it) and you must use a binary format if you really want to use a matlab
format, to save to...

I suppose that '-mat' should be made a synonym for '-mat-binary' though
to get rid of the two different version of the save command above. If
you are really interested in this, then I attach a patch against the
current octave CVS with this change plus a couple of minor documentation
fixes.

David
