[Numpy-discussion] Interface for numpy C-API <-> simple C++ matrix class

[Stefan H. <Ste...@un...>]

Hello,

we would like to write routines processing numerical python arrays in
C++, so that at least boundary checking can be enabled at runtime.
While there are a lot of matrix libraries available for C++, I could
not find the glue that interfaces such a library to the C-API of
numerical python. Seamless access to a minimal C++ library would make
the C++ part of programming much easier.

Has anyone already written some wrapper/glue code?

Thanks and best regards,

Stefan

That's clear i had the same problem long time ago,
and i written a small wrapper to the blitz library (www.oonumerics.org):
i hadn't time to iron out all the details so it isn't ready for general
release, but it works.
I'm courrently using some sort of template skeleton to write modules in
python for my phd (it is 4d digital image processing): if you like to help
me to develop it in a usable way this should be useful for other people as
well.

I think someone else has developed such a glue, under scipy (isn't?): just
look at that.

regards,
antonio

Weave optionally uses blitz arrays to represent NumPy objects:

   www.scipy.org/site_content/weave

Maybe something there will be of use.

You might want to check out the Boost Python Library.  It is peer reviewed
and seems to get most things correct.

It should make writing wrappers a lot easier.

Ummmm, it helps if I include the URL.  Sorry.
