摘要
该文对一类广义对角占优矩阵M,给出了迭代矩阵M-1N的谱半径的上界.特别,当M是严格对角占优时,证明了所得到的估计值总比通常用作谱半径的估计值要好.
In this paper we present the estimates of upper bounds of the spectral radius for the iteration matrix M-1 N for some generalized diagonally dominant matrix M . Particular-ly, we show that our estimate of the spectral radius is better than those in the references.
