摘要
对非负不可约矩阵的谱半径估计进行了研究,得到一种极限估计方法,并给出了证明,因此在计算上可得到比以前有更高精确度的估计式,而且有一定的理论研究价值,并用数值算例也验证了这一结论.
This article discusses a limited methed of estimating the spectrum radius of the nonnegative irreducible matrices and confirms its validity in theory.The methed has better accuracy in caculation than previous studies and is also very useful in theory.Based on those methods,two numerical examples are proposed to illustrate it.
