恒定行和矩阵的特征值定位

Eigenvalue Localization for Matrices with Constant Row Sum

恒定行和矩阵是指矩阵每行元素的和都为同一个数,提供了恒定行和矩阵特征值定位的一种方法并给出相关的结果,通过例子说明这种方法在矩阵特征值定位方面的有效性.

A matrix is constant row sum if all its row sums are constant.In this paper, eigenvalue localiza-tion results and methods for matrices with constant row sum are provided, and the numerical examples are given to show the efficiency of the proposed methods in eigenvalue localization for matreces.
