Hey all.
I would just like to thank you all for extremely good feedback on my problem
with optimizing loops. Thank you all for being so helpful.
Cheers, Trond

Trond,
See if the attached file contains something close to what you need. It
has no loops at all; I have not timed it, but it should be quite quick.
I have given it only a cursory check, so I don't guarantee it works
correctly.
Depending on how your particular NetCDF interface works, you m

Hi again.
I have attached the function that the FOR loop is part of as a python file.
What I am trying to do is to create a set of functions that will read the
output files (NetCDF) from running the ROMS model (ocean model). The output
file is organized in xi (x-direction), eta (y-direction), and
I would definitely suggest using scipy's weave.inline for this. It
seems like this particular function can be translated into C code
really easily, which would give you a HUGE speed up. Look at some of
the examples in scipy/weave/examples to see how to do this. The numpy
book also has a section

Hi all.
This is my first email to the discussion group. I have spent two days trying
to get a particular loop to speed up, and the best result I got was this:
tmp1=zeros((eta,xi),float)
tmp2=zeros((eta,xi),float)
tmp1=tmp1+1
tmp2=tmp2+1
for i in range(xi):
for j in range(eta):
