nsolve and nonlinsolve

[homer...@gmail.com]

Hallo,

I hope this is no double post, my previous thread is not displayed in the group.

Will nonlinsolve from sympy.solvers.solveset replace solvers.nsolve?

I could not find that in the documentation. I tried to run some examples
for nonlinsolve but get an ImportError after

from sympy.solvers.solveset import nonlinsolve

I tried SymPy 1.0 from PyPI and from Gohlke, same with both versions.
The documentation for SymPy 1.0 says that the function is available.
Or is it only available in SymPy 1.0.1.dev ?

Kind regards,
Joe

You have to install the latest version of SymPy to use `nonlinsolve` , the link for latest version is this . `nsolve` is numeric solver , `nonlinsolve` solves non linear system of equation symbolically.

Hi Shekhar,

Is nonlinsolve good to use? coz it does not seem to be in any Sympy setup file, nor the one you pointed to nor the live sympy version.
If it exists, do you have any idea where to download it? and how to update the existing Sympy to the new version?

Thanks,
Mohammad

nonlinsolve is only in the development version. See
http://docs.sympy.org/latest/install.html#git for instructions on how
to get it. It will be included in the next stable release.
