任何Python等价的Math :: Polynomial :: Solve？ [英] any Python equivalent of Math::Polynomial::Solve?

问题描述

在谷歌搜索非线性方程求解器时，我发现

Math :: Polynomial :: Solve in CPAN。这似乎是一个很棒的小模块，除了

它不是Python ...我特别在寻找它的poly_root（）

功能（它解决了任意多项式） ）。有谁知道

a实现它的Python模块/包？


只是

解决方案

只需

SciPy能做你想做的吗？特别是Scientific.Functions.FindRoot [1]&

Scientific.Functions.Polynomial [2]


问候，

（嗯，我的印象是scipy！= Konrad Hinsen'的科学

模块。）


我玩过[1]但是只有计算一个根，我需要所有

根（特别是对于一个五次方程）。 [2]似乎不是一个

求解器？

While googling for a non-linear equation solver, I found
Math::Polynomial::Solve in CPAN. It seems a great little module, except
it''s not Python... I''m especially looking for its poly_root()
functionality (which solves arbitrary polynomials). Does anyone know of
a Python module/package that implements that?

Does SciPy do what you want? Specifically Scientific.Functions.FindRoot [1] &
Scientific.Functions.Polynomial [2]

Nick.

(Hm, I had the impression that scipy != Konrad Hinsen''s Scientific
module.)

I had played with [1], but it "only" calculates one root, and I need all
roots (specifically, for a quintic equation). [2] doesn''t seem to be a
solver?
