Will Cython be compatible with OpenMP? I tried with weave some time back
and failed miserably. Has anyone tried with ctypes?
Cheers,

It's not so much an abjection (I think), but the fact that pyrex/Cython
really are different beasts, with different goals.

Ok, I see, thank you Pierre.
I thought scipy.stats would have been a widely used extension so I
didn't really consider the trivial possibility that simply wasn't
compatible with ma yet.
I had a quick look at the code and it really seems that ma handling can
be achieved by replacing np.asarray wi

Giogio,
You're right: there's no full support of masked arrays in Scipy y
Hi Everybody,
I have some arrays that sometimes need to have some of their values
masked away or, simply said, not considered during manipulation.
I tried to fulfill my purposes using both NaNs and MaskedArray but
neither of them really helped completely.
Let's give an example:
from numpy impor
