The whole idea of asarray, is that it should be able to convert properly defined objects without even copying the data. > my own custom class which contains data members, methods and an array > of data (underlying C array) This sounds like EXACTLY the type of object that the array interface is supposed to support. So what you need to do is give your object an array interface: http://numpy.scipy.org/array_interface.shtml once you've done that, asarray() should "just work" and therefore all of MPL should just work. However, I would post a question about this to the numpy list -- there is an effort at the moment to have an n-d buffer protocol defined for Python 3.0. http://projects.scipy.org/mailman/listinfo/numpy-discussion I'm not sure at this point whether you'd be best off implementing the above interface or the new buffer protocol that's being discussed: http://projects.scipy.org/scipy/numpy/browser/trunk/numpy/doc/pep_buffer.txt The numpy folks will be able to help. By the way, this is a good example why the above PEP is a good idea! -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception [EMAIL PROTECTED] ------------------------------------------------------------------------- Take Surveys.
