摘要
本文对Ostrowski给出的关于矩阵的特征值估计作一些讨论，特征值分布特性被揭示，进而得到了一个判定矩阵非奇异性的充分条件．
In this paper, we make some discussion for the estimate of the matrix eigenvalue, that isobtained by Ostrowske, some distribution character of the eigenvalue are described, then a sufficientcondition to determine nonsigularity of the matrix is given.
