python interface to c++ class

[Thooney Millennier]

Hello, everyone.
I am now working on building Python interface
to my C++ matrix library.

for example In C++,we can enjoy following
operations.
(f_matrix: matrix class for float, d_matrix: for
double)

   1. f_matrix x1,x2; float y; x2=y*x1; (operation
between different types)
   2. x1(1,2)=3.4; (substitution for matrix
element)
   3. d_matrix z; z=x1;
   (auto conversion from float matrix to another
type(d_matrix))

Is it possible by "PyNumberMethods" ?
I would like to know how to implement above with
Python.

Thanks for reading.
