[GiNaC-list] simplify_indexed and inheritance

Hi guys, I have a simple question. I would like to construct a derived class of indexed type, folowing the final part of tutorial. How can I inherit simplify_indexed()? For example: class Myclass : public indexed{ .... } Myclass(ex b, idx a), indexed(b,a) { ... } Myclass::simplify_indexed() { I don't know!!! } Thanks in advance, Marco ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/
