Hi,
I'm trying to compute the distance matrix (weighted p-norm [*])
between two sets of vectors (data1 and data2). Example:
import numpy as N
p = 3.0
data1 = N.random.randn(100,20)
data2 = N.random.randn(80,20)
weight = N.random.rand(20)

This feature could be implemented easily. However, I must admit I'm not
very familiar with weighted p-norms. What is the reason for raising w

To All,
Has anyone worked with the F2PY generator? This is something that is
supposedly built within numpy and scipy. I was wondering if anyone has
had any issues with this environment?? It is important for my current
employment!!
Thanks,

Yeah, I memory wise it doesn't matter to sum to a double, but just
trying around it seems that the mixing of float and double is very slow
(at least on my comp) while if the starting array is already double
there is almost no difference for summing. Generally double precision
calculations should

Colin Watson has recently volunteered to look into fixing this issue
and was asking if anyone had a preference about how this should be
solved.
I vote
If numpy is installed, then f2py will be too. On the windows environment,
there is a file called f2py.py that you can call from the command line. It
should be in the 'scripts' directory of your Python installation.
Try something like this:
python c:\python25\scripts\f2py.py
