Matlab has some interesting behavior with functions that overload
built-in functions. For example, given a file sin.m (not in an @CLASS
directory, just somewhere in the path):
function y = sin (x, y)
disp ('Matlab is sinful');
then
sin
sin ('foo')
sin ('foo', 'bar')
sin ('foo', 2)
etc. all call the .m file version and
sin (1)
calls the built-in function. But
sin (1, 2)
sin (1, 'foo')
fail with a 'too many arguments' error.
So overloading seems closely tied to the way objects work, so I think
it will really only work the same in Octave when we have Matlab
compatible objects (which I am trying to work on now, but will not be
merged with the main CVS trunk until after 3.0 is released.
