摘要
给出了一个计算不可约非负矩阵谱半径的拟幂型算法,在算法的每步迭代中引入一个适当的变参数,与幂型算法比较不但适用范围更广,在基本不增加计算量的情况下提高了计算的稳定性和效率.
A quasi-power algorithm for the spectral radius of the irreducible nonnegative matrix is given,and an appropriate variable parameter is introduced in each iteration.Compared with the power algorithm,it not only has a wider application range,but also improves the efficiency of convergence without increasing the amount of calculation.
