Thanks, I looked now through quite some SWIG examples and I was able to
get a matrix/array from numpy into C++ (with the very good documentated
examples in numpy-svn/numpy/doc/swig).
However, I did not manage to get an array out of C++ to python without
copying so far.
In the examples cited above it's only shown how to generate a new one
dimensional array and return that.
Do you maybe have some links (from the mails here and on) where these
features are explained ? Or modules which are examples for such use-cases ?
Thanks for any hint,
LG
Georg
