摘要
利用非奇异M矩阵的逆矩阵A^(-1)的元素的新估计式,给出不可约M矩阵B与A^(-1)的Hadamard积的最小特征值的新估计式τ(B°A^(-1)),理论证明了所得的估计式提高了李华给出的相应结果。
Using the new estimate of the elements of the inverse matrix of a nonsingular matrix , A new estimate of the minimum eigenvalue of the Hadamard product with an irreducible matrix and is given. The theoretical proof of this paper is to improve the corresponding results given by Li hua.
