numpy.polydiv

numpy.polydiv(u, v)

返回多项式除法的商和余数。

注解

这是旧的多项式API的一部分。从版本1.4开始，新的多项式API在 numpy.polynomial 首选。差异可以在摘要中找到 transition guide .

输入数组分别是“分子”（被除数）和“分母”（除数）多项式的系数（包括任何等于零的系数）。

参数

u数组或poly1d

被除数多项式系数。

v数组或poly1d

除数多项式系数。

返回

q恩达雷

商的系数，包括等于零的系数。

r恩达雷

余数的系数，包括等于零的系数。

笔记

两个 u 和 v 必须是0-d或1-d（ndim=0或1），但 u.ndim 不平等 v.ndim . 换句话说，所有四种可能的组合- u.ndim = v.ndim = 0 ， u.ndim = v.ndim = 1 ， u.ndim = 1, v.ndim = 0 和 u.ndim = 0, v.ndim = 1 -工作。
