An iterative improvement algorithm for Perron root of nonnegative matrices
Pages: 30-33
Year: Issue:  1
Journal: Journal of Southwest University for Nationalities(Natrual Science Edition)

Keyword:  非负矩阵Perron根迭代;
Abstract: 目前关于非负矩阵Perron根即最大特征值的估计和计算已提出了很多方法.利用对角相似变换,给出了一个求非负矩阵Perron根的迭代算法,可以根据精度的要求迭代足够多次得到所需要的近似值.并从理论上证明了它的收敛性,同时给出一种改进的方法,使得在相同的精度下尽可能的减少迭代次数.最后,用数值实例验证.
