摘要
讨论n×n阶非负矩阵的谱半径估计,给出估计其界值的新方法,该方法易于计算且能得到比"非负不可约矩阵谱半径的估计"一文中精确度更高的界,并用数值例子验证了这种方法的有效性.
This article discusses estimating spectrum radius for n X n nonnegative matrix. The new method to estimate dividing value is presented. The new method is easy to calculate and can obtain higher precision compared to the article ＂Two-sided Bounds for the Spectral Radius of Nonnegative Irreducible Matrices＂. The new method is confirmed its validity with the value example.
