摘要

该文利用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.
        A new upper bound on the spectral radiusρ(A B)for the Hadamard product of two nonnegative matrices Aand Bis given by using Gerschgorin theorem.Numerical example shows that the new result improves several existing results in some cases.
