求鳞状循环因子矩阵的极小多项式的算法
An algorithm for Finding the Minimal Polynomial of a Scaled Circulant Factor Matrix
摘要
Abstract
In this paper,the scaled circulant factor matrix over any field is introduced. Algorithms for computing the minimal polynomial and common minimal polynomial of this kind of matrices over any field are presented by means of the algorithm for the Grobner basis of the ideal in the polynomial ring,and an algorithm for finding the inverse of such matrices are also presented,which can be realized by CoCoA 4.0,an algebraic system,over the field of rational numbers or the field of residue classes of modulo prime number. Numerical examples show the effectiveness of the algorithms.关键词
