| 摘 要： | 首先给出两个矩阵A,B的Hadamard乘积的定义,然后给出M-矩阵在Hadamard积下的几个运算性质,运用矩阵Hadamard乘积及特殊矩阵理论,将M-矩阵在Hadamard积下的若干性质,推广到其他类型的特殊矩阵上。获得了M-矩阵,L-矩阵,H-矩阵和Hermitie-矩阵的几种特征值(q(A),l(A),λ(A))的不等式,以及谱半径ρ(A)、矩阵迹tr(A)满足的几个不等式性质。

| Abstract: | Definition of Hadamard product of A,B matrices and some properties of the Hadamard product of M-matrix were given.By the means of the matrix Hadamard products and theory of special matrix,the properties of the Hadamard product of M-matrix are extended to other special matrices.The inequalities for the eigen values(q(A);l(A);λ(A)) and the inequalities about ρ(A) and tr(A) of M-matrix,L-matrix,H-matrix and Hermitie-matrix are obtained. |
