As a footnote to this query, has the Scons community addressed the problem Scons had working with VS 2008 (=VS9)? No. I'm still facing the same issues, but I'll try to help David Cournapeau with his work on that (he is trying to simplify all Visual Studio supports). Matthieu -- French PhD

[Numpy-discussion] Inplace dot and blas access

2008-08-25 Thread Dan Goodman
Hi all, I'm sorry for what is probably a very simple question but despite looking I didn't manage to find anything. I have some code (solving linear differential equation) which is doing the following operation lots of times: S[:] = dot(A,S)+C here S is a (M,N) matrix, A is (M,M) and C is

2008-08-25 Thread Catherine Moroney
This almost works. Is there a way to do some masking on tiles, for instance taking the maximum height of each 2x2 square that is an odd number? I've tried playing around with masking and where, but they don't return an array of the original size and shape of tiles below. Catherine Perhaps

[Numpy-discussion] Converting audio data to array for further processing

2008-08-25 Thread Dan Colesworthy
Hello all, I need an efficient way to convert 24 bit signed audio data to a numpy array for further processing. The data will be in a .wav file, and can be recovered via the python wave module. At that point it is a byte string - likely in little endian order. Somewhere in that data will be
