I don't have a lot of time to respond right now. But here are some thoughts. I'm not sure I'd use SWIG at this point. I'd probably either a) use ctypes to call the C++ library (if it is compiled as a *shared* library) although to be honest I'm not sure if calling a C++ causes any grief. b) byte-the bullet and use Boost python (which other's who have integrated C++ code with Python seem to really like). I've never wrapped my mind around Boost python, though, so I'm not much help there. c) write a custom Tensor class that either inherits from the ndarray or is a mix-in class with the ndarray as a component. If it were me, I'd probably be doing a combination of a and c. I've just finished the chapter in my book that covers and compares f2py, weave, pyrex and ctypes integration. I've been waiting on finishing this chapter before sending updates. You should get the update by the end of the week.
