广义对角占优阵和广义次对角占优阵等价条件的注记

Notes on an equivalence condition of the generalized diagonally dominant matrices and the generalized subdiagonally dominant matrices

指出了广义对角占优矩阵与广义次对角占优矩阵之间的关系,对广义对角占优阵和广义次对角占优阵的一个等价条件给出了较简捷的证明方法.

In this paper, we point out the relationship between generalized diagonally dominant matrices and generalized subdiagonally dominant matrices, in addition, we give a succinct proof to an equivalence condition of the generalized diagonally dominant matrices.
