摘要
计算矩阵特征值的常规方法就是求其相应的特征多项式的根.然而,当矩阵的特征多项式次数超过5次时,其根的求解没有公式可循,因而计算相当困难.为此,通过讨论不可逆矩阵特征多项式的结构问题,从而得到其特征值计算的一种便捷方法.
The method of calculating the matrix Eigenvalues is finding the corresponding characteristic roots of a polynomial. However, there is no formula to find the root of characteristic polynomial of the matrix, when it＇ s the degree more than five times, thus very. diffieuh to calculate. In this paper,we researched the structure of characteristic polynomial on non-invertible matrix was, and given a simple computing method.
