Hi Holger - I put together some header-only classes for this back when I used to do a lot of C++ and numpy. They are part of the "esutil" package but you could actually just pull them out and use them http://code.google.com/p/esutil/ The first is a template class for numpy arrays which can create and import arrays and keeps track of the reference counts http://code.google.com/p/esutil/source/browse/trunk/esutil/include/NumpyVector.h The second is similar but for void* vectors so the type can be determined at runtime http://code.google.com/p/esutil/source/browse/trunk/esutil/include/NumpyVoidVector.h There is also one for record arrays http://code.google.com/p/esutil/source/browse/trunk/esutil/include/NumpyRecords.h Hope these are useful or can give you some ideas. -e -- Erin Scott Sheldon Brookhaven National Laboratory _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
