矩阵Hadamard积的谱半径上界新估计

摘要

矩阵的Hadamard积是矩阵理论研究及其应用的重要课题之一,本文给出了非负矩阵与非奇异M-矩阵的逆矩阵的Hadamard积的谱半径新的上界估计式,理论证明新的上界估计式精确度有所提高.%The Hadamard product of matrix is one of the important topics in the research of matrix theory and its application.In this paper,Some new upper bounds of the spectral radius of the Hadamard product of non-negative matrix and the inverse matrix of nonsingular matrix are given.It is proved theoretically that the accu-racy of these new upper bounds are improved.
