This makes me ask something that I always wanted to know: why is weave
not the preferred or encouraged way ?
Is it because no developer has interest in maintaining it or is it too
onerous to maintain ? I do not know enough of its internals to guess
an answer. I think it would be fair to say that w

Hi,
Someone told me that on this page, there was a new parameter to
numpy.sum: keepdims=False
http://docs.scipy.org/doc/numpy/reference/generated/numpy.sum.html
Currently the doc don't build correctly this page. Can someone fix this?
He gived the link to the google cache that showed it, but the

SWIG can read C or C++ header files and use them to generate wrapper interfaces
for a long list of scripting languages. It sounds to me like you want to go
the other direction -- i.e. you have a code prototyped in python and you want
to convert core kernels to C++, perhaps to improve e

if you're using SWIG, you may want the numpy.i SWIG interface files,
they can be handy.
but I probably wouldn't use SWIG, unless:

Hi Ralf,

Hi, I plan to migrate core classes of an application from Python to C++
using SWIG, while still the user interface being Python. I also plan to
further use NumPy's ndarrays.
The application's core classes will create the ndarrays and make
calculations. The user interface (Python) finally receives
Dears,
Though it might sounds strange, but the eigenvectors of my 2X2 matrix is rather
different if I get it calculated in a loop over many other similar matrices:
for instance:
matrix:
[[ 0.6000+0.j -1.97537668-0.09386068j]
[-1.97537668+0.09386068j -0.6000+0.j]]

Hej Val,
Thank you very much for your replies.
Yes, I know that both eigenvectors are correct while they are indeed related
to each other by unitary transformations (unitary matrices).
Actually, what I am trying to do is to evaluate the Berry phase which is
closely related to the gauge chosen
