摘要:
把2个非负矩阵Hadamard积谱半径以及M矩阵的Fan积的最小特征值的估计推广到多个矩阵,得到新的界值估计式,数值算例表明所得的估计式在一定条件下比现有的估计式更为精确.
Abstract:
A new upper bound of spectral radius of Hadamard product and a new bound for the minimum eigenvalue of Fan product of more matrices are obtained on the basis of two matrices.Numerical examples show that these new bounds are more accurate than several known estimating formulas.
