I have just committed the latest version of numpy.i (a swig interface file for bridging between C arrays and numerical python) to the numpy svn repository. There are three relatively new features that are now supported:
* It is now possible to wrap functions that expect integer arguments and have swig generate wrappers that allow you to provide numpy array scalars. * A new ARGOUTVIEW suite of typemaps is provided that allows your wrapped function to provide a pointer to internal data and that returns a numpy array encapsulating it. This is potentially dangerous, but necessary in some situations for very large data buffers. * New typemaps are provided that correctly handle FORTRAN ordered 2D and 3D arrays. Tests for the ARGOUTVIEW and FORTRAN ordered arrays have also been added, and the documentation (doc/numpy_swig.*) has been updated to reflect all of these changes.
