[Numpy-discussion] matrix product in parallel?

2011-11-18 Thread Nicolas Bock
Hello list, is it possible to get numpy to do a matrix product in parallel? I presume that the multiply in the back-end is really done by dgemm() or equivalent, so is it possible to use a parallel dgemm() there? Thanks, nick ___ NumPy-Discussion mailin

Thanks to all people for this very nice discussions. the solutions are more that what I want!! and help me to clarify some concepts, and really begin to use class as a beginner :) I would say either Olivier or denis's solution can solve my problem completely. cheers, Chao 2011/11/18 denis >

[Numpy-discussion] Subclassing ndarray

2011-11-18 Thread Fabrice Silva
Hi, I wish I could subclass ndarray so that I can use the ufuncs, but that I could ensure the array remains Fortran contiguous, and that the number of dimension is always 3 (even if the dtype can be more complex than a simple numerical type). My intention is to deal with fields that can be scalar,

I've been in touch with Martin Reinecke, author of the libpsht code for spherical harmonic transforms, about licensing issues. libpsht itself will remain under the GPL, but he is likely to release his C port of FFTPACK under BSD in the near future, as it is based on the public domain FFTPACK.
