Example of sending a numpy array to C code using Cython. Build + tested on linux, will need recompilation of library for other operating systems.

Running python test.py will check correctness of 4 C functions taking in numpy arrays.

If you want to recompile the library then use python setup.py build_ext --inplace. You will need Cython set up for this to work.

basic_funcs.cpp and basic_funcs.hpp are where the C code is written, other c++ files are generated during compilation via Cython.

The .pyx file provides the wrapper functions to glue numpy to C.

Pleasse expand if you find anything useful to add.
