Well, I need. inheritance and polymorphism.. yes that's what i meant by
"where the class of x determines the choice of the function.'

I just wondered, whether octave checks for the first argument only.
And i was confused, that i did nowhere in the docu find a word about the
search mechanism.
Something like:
"If the first argument arg1 has class <cls> (determined by function
class(arg1)),
then the function definition is searched for in folder @<cls> and
subfolders recursively. "

Is this the truth?

Also it seems to me as if only member methods are supported. Right?

Ernst
