非奇异M-矩阵的逆矩阵和M-矩阵的Hadamard积的最小特征值下界估计
Estimate of Bounds on the Minimum Eigenvalue of the Hadamard Product of Inverse Matrix of Nonsingular M-matrix and M-matrix
摘要
Abstract
Some new lower bounds of the minimum eigenvalues of the Hadamard product of inverse matrix of nonsingular M-matrix and M-matrix are given.These estimating formulas of the bounds only depend on the entries of matrices.Numerical examples show that the new estimating formulas improve the conjecture of Fiedle and Markham effectively,and also improve the other related results.关键词
