Well, if I may have a say, I think that an open source project is
especially open when users as developers can contribute to the code
base and can participate in discussions on how to improve the existing
designs and ideas. I do not think a project is open when it crumbles
down into politics.. I ha

Hi,
libmkl_lapack.so is added in site.cfg and now the matrix function is not

Hi guys,
I have a question regarding subclassing of the numpy.matrix class.
I read through the wiki page,
http://docs.scipy.org/doc/numpy/user/basics.subclassing.html
and tried to subclass numpy.matrix, I find that if I override the
__finalize_array__ method I have problems using the sum method
I found the 2d iterator definition active in numpy 1.6.1. I'll test it.

My use case is a biliterl filter: It is a convolution-like filter used mainly
in image-processing, which may use relatively large convolution kernels (in the
order of 50x50). I would like to run the inner loop (iteration over the
neighbourhood) with a direct indexing (in a cython code) rather th

The MA stuff can "leak through" only if the user makes use of a library

It could, at least in principle. The underlying translate function is
called often enough that a slight different can be significant.
