#35926 — numpy has got newtonsmethod?

my question is can we import newtonsmethod from nympy or sciPy?

I'm guessing it would show you flailing around and _not_ typing "numpy
newton's method", because that's all it took to bring up the direct
link to the scipy documentation on importing & using it (first link),
as well as full code samples of variants implemented directly in
numpy.

Well, my "email id" (I presume you mean "email address") is perfectly
visible in the headers of all my posts to this list/newsgroup. But
that doesn't give you the right to email me a list of everything
you've searched for, downloaded, etc. Plus, it wouldn't help your
case; your posts carry no indication that you have learned from your
web searches, so it doesn't matter what you've done. Your posts also
bear no suggestion that you have read esr's excellent article on
asking questions, which is why I reiterated it.

So don't show me your efforts. Show me that you've learned from them.

Hi,
After successfully installing SciPy
http://www.scipy.org/Download
you should be able to import the respective modules and use this
functionality such as
http://docs.scipy.org/doc/scipy/reference/generated/scipy.optimize.newton.html

you may also consider

mpmath
http://code.google.com/p/mpmath/
http://mpmath.googlecode.com/svn/trunk/doc/build/calculus/optimization.html

SymPy
http://sympy.org

or maybe some OpenOpt software
http://openopt.org

or other related libraries/frameworks available in python.

I am not at all competent to decide about the suitability for your
originally posted problem, but I guess, you may be able to find it out
based on your requirements and the features supported by these
libraries.

hth,
  vbr

thanks. . 

but how to instal scipy. because its in .rar form. .i have extracted the files to the place where python2.7 is installed. . but everytime i write import sciPy. .it give me error. . 
nd regarding ur question. .

its a long story telling u why i have just ask this breif question. . anyways thanks . .waiing for ur reply. .

i just want to iterate my complex equation. .

how can i import newtonsmethod from numpy as numpy is successfully insalled. .:)

If you want help, you have to remember we can't magically detect your
development environment. Of course, you could always just read
http://www.scipy.org/Installing_SciPy and report back with explicit
information on _what didn't work_.

Repeating the question because you're not listening to the answers
given is growing tedious. Vlastimil provided you with a _direct link_
to the relevant documentation: http://docs.scipy.org/doc/scipy/reference/generated/scipy.optimize.newton.html

If you can't import from scipy, then _fix that problem first_, because
that's what you need to be able to do the rest.

I assume (based on the traceback you posted), that you are using
windows; in that case you can use the appropriate ready made
installers for SciPy, instead of the source files; see.:
http://sourceforge.net/projects/scipy/files/scipy/0.11.0/
e.g.:
scipy-0.11.0-win32-superpack-python2.7.exe

Please read the error message. It tells you exactly what you need to do.

You cannot import scipy while being in scipy source directory; please 
exit the scipy source tree first, and relaunch your python interpreter.

Do you understand what a source directory is? It is a directory (a 
folder) with the source code in it. Leave the scipy directory, and re-
start Python, then try importing scipy.
