代数方程求根的一个新的数值解法

摘要

In this paper, the authors transform the problem of extracting the roots of algebraic equations into the problem of extracting the characteristic mots of the matrixes by suitable method. By using the QR method of extracting the characteristic roots of a matrixes give the numerical method for extracting all roots of algebraic equations was obtained.%通过适当的方法将代数方程的求根问题转化成求矩阵特征根问题，然后利用求矩阵特征根的QR方法给出了一个同时求出代数方程的全部根的方法。
