摘要
在研究弱严格对角占优矩阵的内部结构、分析弱严格对角占优矩阵与H-阵的关系中,得出了弱严格对角占优矩阵是H-阵的几个充分条件.
The internal structure of weakly strictly diagonally dominant matrix is studied. Sufficient conditions for weakly strictly diagonally dominant matrices being H - matrices are established by analyzing the relationship be- tween weakly strictly diagonally dominant matrix and H- matrix.
