[C++-sig] member function template question.

[Ralf W. Grosse-Kunstleve]

Your example has several layers of complexity. I believe the main trick you
need to know is how to use a cast to tell the compiler what you want. E.g.:

  template <typename FloatType>
  bool
  is_positive_definite(
    vec3<FloatType> const& eigenvalues,
    FloatType const& tolerance);

  def("is_positive_definite",
    (bool(*)(vec3<double> const&, double const&)) is_positive_definite);

This is a bit cumbersome but somehow you have to define which FloatType you
want to use since you are crossing the boundary between compile-time
polymorphism and runtime polymorphism.

If you don't like the casts you can also define thin wrappers. This works for
both "normal" functions and member functions.

I don't know how this is handled by Pyste. Maybe someone else can help?

I am also not an expert on dealing with raw pointers, in particular void* needs
special attention. I think there is something about void* in the FAQ that you
might want to read.
