if for example you have your load command whithin a for or while loop
you could do something like the following to just skip to the lext  
step in the
loop whenever the file does not exist or is empty

for ii=1:maxii
%% do stuff
try

        f = load ("file_that_maybe_does_not_exist")

catch

        warning(lasterr ())
        continue

end_try_catch
%% do stuff
endfor
