Hi all,
I just wrote ctypes bindings to fftw3 (see
http://projects.scipy.org/pipermail/scipy-user/2009-January/019557.html
for the post to scipy).
Now I have a couple of numpy related questions:
In order to be able to use simd instructions I
create an ndarray subclass, which uses fftw_malloc to
Doh! That's embarrassing!
Thanks!

PS I hope "disappointed" did not sound so strong

Not in my opinion: Travis wrote a book,
which is what is being cited.
The docs link is in fact to the same tramy site.
I must add that IMO, it would be a courtesy

Thx for the links, but I'm afraid I need something more basic than
that. For example, I'm referring to Python as:

Hello,
I would like to operate in an easy and efficient way (without python loop) with
arrays of matrices.
Suppose a and b are some arrays of N1*N2 matrices of size 3*3, I would like to
calculate inv_a and dot_ab, which would be arrays of N1*N2 (3*3)-matrices,
such as :
inv_a[i, j] = np.lin
Correct, however other areas of the application expect an empty list to be
present, otherwise I would have used None.

Yes fair point, but when it's a empty list and new elements are replaced
with a new list instance it's fine, especially as [[]]*10 is
significantly faster than [[] for i in xrange(10)] as I was previously

In fact I think that's partly answered my question [[]]*x must create a list

Hi,
Don't remember that you are using the same list in each element of the
outer list. If you don't want this, use [[] for i in range(5)]. I
don't think there is another way in C either (or too complicated).

Hi,
Quick question, I've been doing a fair bit of extension writing in C
recently, but wondered how best to implement:
>>> l = [[]] * 5
to create a list of a given length containing the initialization variable
desired.
A loop seems the straight forward manner, but I would have thought there was
35 matches
