I've done a version of nipals algorithm in python (i'ts a translation of
a matlab routine in brereton made by Riccardo Leardi). far from perfect
(my transport i mean) but working (I've tested on my datasets and it
runned ok) you can download it at www.chemometrics.it.
Hope it will help and if yo
first of all sorry for cross posting
As I wrote some time ago we are trying to write a book proposal about
the use of python/scipy/numpy in chemometrics and analytical chemistry.
Since now I've received positive answer from eight authors and the only
"missing" chapter is one about the use of pyt
ll around

P.S.: (sorry for cross posting)

If you are using it for making a PCA,
why dont' you try to use nipals algorithm ?
(probably a silly question , just wanted to give help :)

Thanks Gael,
I dont' use Ipython, but Ide in interactive mode and everything is fine
(changed matplotlibrc and then se switch on in configuration). I just
meant hat if you dont' know it or dont' pay attention to start with the
correct shortcut etc. etc. you dont' have an "immediate" interactive
All good points stated here.
Unfortunatly I'm not able to contribute, and as stated also in other
thread, scipy/python was not born for being a clone of matlab (uhmm well
probably matplotlib at first was). What would be the "killer" distro for
matlab ?
An updated distro with numpy/scipy/matplotl
Thanks for the reply I will sure try to use it and so some small software.

Hello Dear All,
I just have a question for all that uses python/numpy/scipy/matplotlib
for making science.
I use with no problem in my computer python+numpy+scipy+matplotlib and
I'm very satisfied with them.
I was a matlab user. I still not have unearthed the power ot python but
I'm happy to u

Hello to all,
I've thread that apperead some time ago on this list about matlab and
teaching.
I've discovered python recently and translated part of the routine I
use in python (www.chemometrics.it).
Some of my collegue asked me if I could show them how to use python. For
matlab user I guess th
inally let me say that any mirroring or hosting
will be greatly appreciated.
I hope that this initiative will be useful ;)
Best Regards
Giorgio Luciano

Yes it worked, sorry for bothering. the problem was theI used round with
no underscore.. and so I made confusion with the two command
Thank a lot !!

I've posted also to scipy group but with no luck.
At first I thought it was an easy task but...
I've to round the numbers inside of a 2d array but nothing seems to
work. the only message I've found in the archive is an old function
custom made for doing that.. wouldn't be useful to have it also i
Here's the runnable example
Everything work fine with installed
python 2.5
matplotlib 0.87.7
numpy 1.01scipy 0.5.2
Cheers

this module plots leverage for a regression module (only two steps in
the grid since it's only a try to compare with a matlab file I have)
# plots leverage plot (3d
Ok thanks Swen
I will try
and sorry for not starting a new thread.. I'm still a newbie with
mailing list too :)

I was converting a matlab file to my new favority scientific language
Numpy :)
In the old file I created a matrix on the fly. I know that Numpy and
python cannot do that so I found a workaround
here's the code
lev2=empty((1,h))
ir=1
for j in arange(1,nstep+2):
#a=gr[[arange(ir-1,ir+nstep)],:

Today I've also posted a question to scipy groups because I've thought
I've found a solution but
this work good
bar(N, b1[:,0], width, color='r', yerr=binterv)
s3=find(sig1[:,arange(ini,c)]<=0.001)
b1=b.flatten()
#if s3!=[]:
for i3 in arange(len(s3)):
text(s3[i3], b1[s3[i3]+
19 matches
