摘要
非负矩阵谱半径的估计是非负矩阵理论中重要的课题。对Frobenius界值方法加以研究,给出了一种易于计算且能得到较紧的界的方法,并通过数值算例与以往的结果进行比较,有一定的精确性。
Computing the bounds for the spctral radius is active and important part in the theory of nonnegative matrice.The bounds for the spctral radius of nonnegative matrix based on Frobenius theorem are studied.A new bound is presented to get two-sided bounds more easily and tightly.Finally,A numerical example is given to illustrate the effectiveness by comparing with the previous results.
