迭代矩阵谱半径上界的新估计
A new estimate of the upper bound of iterative matrices
摘要
Abstract
The upper bound for spectral radius of iterative matrix M-1 N is estimated when M is an α- diag-nally dominant matrix. The esimations of p(A-1) and ρ(J) are obtained by calculating sufficient conditions for | λ(.M-1N) | ,and the numerical example illustrates the effectiveness of the criteria.关键词
