摘要
本文利用Brauer定理和Gerschgorin定理给出了非负矩阵A和B的Hadamard积的谱半径新的上界.数值算例表明新结果在一定条件下改进了现有的一些结果.
In this paper some new upper bounds to the spectral radius of the Hadamard product of two nonnegative matrices are studied by using Brauer’s theorem and Gerschgorin’s theorem.The Numerical example shows that the new results improve some existing results in some cases.
