Hi all,
I have added to the ticket [1] a script that compares the proposed
setmember1d_nu() implementations of Neil and Kim. Comments are welcome!

Hi,
Is anyone getting mails of the SVN commits? I've gotten 1 spam message from
that list, but no commits.

I found the solution I needed for my peculiar case after reading your email
based of the following stages:
I have a N x N frequency-domain matrix Z
1. Use fftshift to obtain a DC centered matrix
Note: fftshift(fft(a)) replaces np.fft.fft(np.power(-1,np.arange(64))*a)
Zs =
Hi,
I have updated http://numpy.scipy.org/array_interface.shtml to have a
giant warning first paragraph describing how that information is
outdated. Additionally, I have updated http://numpy.scipy.org/ to point
people to the buffer interface described in PEP 3118 and implemented in
Python
Hi Nadav
You can also read the interesting discussion at
http://projects.scipy.org/numpy/ticket/748
which also contains some padding code.
I still disagree with the conclusion, but oh well :)

Hi,
The idea behind the current syntax was to keep things as close as
possible to Python/NumPy, and only provide some hints to Cython for
optimization. My problem with this now is that a) it's too easy to get
non-optimized code without a warning by letting in untyped indices, b) I
think the

Well, I suppose that, provided that Cython could perform the for-loop
transformation, giving support for strided arrays would be relatively
trivial, and the performance would be similar than numexpr

Hey guys, I'm
Greetings,
I am running Windows Vista Ultimate and trying to build numpy from the
SVN branch using MSVC 2003. I have been able to build previously, but
with my latest SVN update I am no longer able to build. My CPU is an
Intel Core2 T7600 @2.33GHz. The error is below.
Hi David,
Currently,
bint.i = __STR2INTCST(ABCD);
It is probably more portable to just initialize the union
union {
char c[4];
npy_uint32 i;
} bint = {'A','B','C','D'};
If you use const union the initialization will be done at compile time.

I've imported some data from a file, and it's in a list called mixfrac. I'd
like to take the Fourier transform of the data, but when I try to take the
FFT of the list, I get this error:

This indicates that the values are strings, so you can't make an FFT
from them. Convert your array to float or double array first.

It's a string array. What does your file look like and how do you import it?

Fixed the problem - I was importing a bunch of numbers from a file, and I
wasn't casting them as doubles. Thanks for the help!

Hi all,
The following code succeeds, while I thought it should fail:
a = np.zeros(6) # real
b= np.arange(6)*(2+3j) # complex
a[1] = b[1] # shouldn't this break?
What is the rationale behind this behaviour?
