1符号与定义 为了行文方便,首先作如下记号约定:n为自然数,In表示礼阶单位矩阵,R^n×n表示所有n×n阶实数矩阵做成的集合。对A=(aij)n×n∈R^n×n,若aij≤0对所有的i,j=1,2,…,n,i≠j成立,
In this paper, the defination of block centrosymmetric matrices is given, and some properties of block centrosymmetric matrices are shown. The relation between nonsingular centrosymmetric H-matrix and their reduced forms is investigated, a simple sufficent condition to testify whether a block centrosymmetric matrix is an H-matrix is given. All these results generalize the conclusions of [2].
