Either should work, I think. If you have multiple processors, the

Hi,

Example

All,
ATLAS 3.7.30 produces two sets of libraries on my machine, the usual bunch
and a set prefixed by pt (posix threading). Am I correct in assuming that
numpy should be linked against the latter?
TIA,

Hi,
how do I find the index of the minimum value of an numpy array?
Example
a = array([1.,2.,0.4,3.])
I want the i=2 since a[i] = 0.4 is the smallest value in a.
Cheers

I was using the superpack from the scipy.org downloads page. I
however found
the library bundle up with g77 and downloaded that so now I get the
import
to work. I expect that there might be other libraries I am missing
but I will have
to deal with t

Dear Sirs,
I'm trying to use Numpy to solve a speed problem with Python, I need to
perform agglomerative clustering as a first step to k-means clustering.
My problem is that I'm using a very large list in Pyhton and the script is
