非负矩阵Hadamard积的新不等式

New inequality for the Hadamard product of nonnegative matrices

利用Brauer定理给出非负矩阵A和B的Hadamard积的谱半径新的上界.数值算例表明新估计式在一定条件下改进了其他文献中的结果.

In this paper, we give a new upper bound of the spectral radius of the Hadamard product of two nonnegative matricesandby using Brauer theorem. Numerical example shows that the new estimating formula improves the results in other literaturesunder certain conditions.
