The boost.python array object is still maintained. However, it has a few problems: 1. All array operations go through python which makes it too slow for my purposes. Phil Austin posted an alternate class on this list which works well since it uses the numpy C API: http://www.eos.ubc.ca/research/clouds/software/pythonlibs/num_util/num_util_release2/Readme.html 2. Only numeric & numarray are supported out of the box, but it is simple to support numpy; just add the following after calling import_array in your extension module: boost::python::numeric::array::set_module_and_type( "numpy", "ndarray" ); 3. If you want the C++-way of dealing with numpy matrices & vectors directly as objects look at either of the following: http://mail.python.org/pipermail/cplusplus-sig/2008-October/013825.html http://mathema.tician.de/software/pyublas Of course, I am biased towards the first approach.
