【Abstract】 Some methods are presented for estimating the minimal eigenvalue of weakly diagonally dominant M-matrices in [1]. In this paper, based on the relationship between the minimal eigenvalue and the spectral radius of nonuegative matrices, we derive some others upper and lower bounds on irreducible, M-matrices.更多还原
