给出非负矩阵A与B的Hadamard积谱半径上下界的新估计式,这些新估计式丰富了ρ(A?B)界的估计。数值算例表明新估计式改进了文献中杜琨的结果。
Given the upper and lower bounds on the spectral radius of new estimator of the Had‐amard product for nonnegative A and B ,these new estimators enrich the estimation of the bound forρ(A B) .Numerical examples show that the new estimation improves the results of Du Kun in liter‐ature .
