Hi,

Hi Sebastian,
I am not sure if there is a function already defined in numpy, but
something like this may be what you are after
def distance(a1, a2):
return sqrt(sum((a1[:,newaxis,:] - a2[newaxis,:,:])**2, axis=2))
The general idea is to avoid loops if you want the code to execute
fast. I hop
Hi,
I'm working with NumPy/SciPy on some algorithms and i've run into some
important speed differences wrt Matlab 7. I've narrowed the main speed
problem down to the operation of finding the euclidean distance
between two matrices that share one dimension rank (dist in Matlab):
Python:

The depreacted function in numpy.lib.utils is throwing a readonly
attribute exception in the latest svn (2627). This is on the Mac OSX
(10.4.6) using the builtin python (2.3.5) during the import of
fftpack. I'm guessing its a 2.3/2.4 difference.

Dear Mary, I suggest using numpy and at the boundaries use
numpy.asarray(yourinput), which will be a quick way to view the data as
a numpy array, regardless of its original type. Otherwise, you could
look at the matplotlib distribution to see how it's done to really
support multiple array packages

you could use the cauchy-schwartz inequality,
which becomes an equality iff the rank above is 1:

Hello. I am a matlab user learning the syntax of

Hi all,
We are getting ready to release some Python software that supports
both NumPy and Numeric.
As we have it now, if somebody wanted to use our software with NumPY,
they would have to download the binary distribution that was built
with NumPy and install that. Otherwise, they have to downloa
Just a guess, you're reading some fits file with pyfits but you didn't declare

We've had the same problem many times. There were a few causes:
* Our clean scripts don't delete c++ files, so generated code was often
not re-generated when we switched to numpy
* Files to generate code had numeric arrays hardcoded
* we were using numerix, and the env var was not set for pa

Hello,
I am attempting to use the svn versions of numpy and scipy, but
apparently (according to http://www.sipfoundry.org/tools/svn-tips.html#proxy )
I am behind a less-than-agreeable web proxy, because I get

Hi,
I have written a number of small modules where I now systematically use

I have in principle used the latest versions of the different

a selection, it crashes on numpy because it seems that the array

There are more exceptions that Numeric is not taking advantage of:
equal, less, greater, ... -> eq, lt, gt, ...
inverse, generalized_inverse -> inv, pinv
In my view it is more importan

The last successful run was with revision 2613. However, revision 2624
appears to have corrected the problem on Solaris.

What is the intended way to disable linking against installed libraries

but that strikes me as less than elegant.
FYI I want to do this to make package building deterministic; not
