I defined the << operator this way (i.e. I wrote "const
Mat::value_type &p" instead of "const polynomial &p"):

ostream &operator << (ostream &out, const Mat::value_type &p)
{
    out << "(";
    for(polynomial::const_iterator i = p.begin(); i != p.end(); i++)
      out << "(" << i->first << ", " << i->second << ")";
    out << ")";

    return out;
}

It didn't help.


Best,
Irek
