If you want matrix multiplication in C++ you are better off using CBLAS
(e.g. Intel MKL, OpenBLAS, Apple Accelerate Framework), Eigen or BLISS. If
you need more linear algebra there is LAPACKE. 

That said, to call NumPy from C++ you must either embed the Python
interpreter in your C++ program or extend Python with C++. The most
relevant options are Python C API, PyCXX, Boost.Python, SIP, Swig, or
Cython. Personally I prefer PyCXX or Cython, but it is a matter of taste.
