摘要
本文是文[1]的继续,讨论了次(对称)正定矩阵的特征值和可逆性,给出了次对称正定矩阵与次正定矩阵的Hadamard乘积的行列式的一个不等式.
This paper is a continuation of paper [1]. The eigen values and the reversibility of metapositive (symmetric) definite matrices are discussed. and an inequality for the determinants of Hadamard product of matapositive symmetric definite matrices and metapositive definite matries is given.
