Although this was mentioned earlier, it's worth emphasizing that if
you need to use functions such as cosine with scalar arguments, you
should use math.cos(), not numpy.cos(). The numpy versions of these
functions are optimized for handling array
Does NumPy 1.5 work with Python 2.7 or Python 3.x?

I think I figured it out. I believe something like the following will do
what you want, iterating across one axis specially, so it can apply a median
function along an axis. This code in particular is for calculating a moving
average and seems to work (though I haven't checked my

Hi Numpy folks,
When working with floats, I prefer to have exact string
representations in doctests and other reference-based testing; I find it
helps a lot to avoid chasing cross-platform differences that are really
about the string conversion rather than about numerical differences.
It's hard to write Cython code that can handle all dtypes and
arbitrary number of dimensions. The former is typically dealt with
using templates, but what do people do about the latter?
I'm trying to take baby steps towards writing an apply_along_axis
function that takes as input a cython

What you typically do is to use the C-level iterator API.

On a somewhat related note, is there a table someplace which shows
which versions of Python are supported in each release of Numpy? I
found an FAQ that mentioned 2.4 and 2.5, but since it didn't mention 2.6

Hello,
I am writing a UFunc creation utility, and I would like to know: is there a
way to mimic the behavior ofPyArray_IterAllButAxis for multiple arrays at a
time? I would like to be able to write UFuncs that take an axis argument and
also take multiple array arguments, for example I want to be
