[Numpy-discussion] (newbie) How can I use NumPy to wrap my C++ class with 2-dimensional arrays?

Oops, I guess I didn't express myself clearly enough: I have used plain 
Python c-api (in my case a list of lists for my 2-dimensional arrays) 
for my typemaps. Sorry for the unclearness. Actually because NumPy is 
not my cup of tea... Especially because Matthieu suggested that I should 
convert my data into a contiguous array.

So no matter what I use, either swig, cython, or.. I still have the 
NumPy issue.

Do you, or someone else, see another possibility?

Raymond
