关于双对称矩阵特征值的估计

On the Estimation of Eigenvalues for Bisymmetric Matrices

对双对称矩阵 ,给出了一系列的特征值估计 ,利用其特殊的性质 ,通过降阶大大减少了计算工作量 .

This paper discusses the following problem:Given n×n bisymmetric matrice A∈BSR n×n ,estimate the eigenvalues of matrix A.Our method requires much less computational work by using the special properties of this kind of matrices.
