摘要
本文在广义对角占优矩阵判定研究的基础上,利用矩阵分块技术,将广义对角占优矩阵的现有结论进行推广,给出块广义对角占优矩阵的判定条件.
generalize generalize Based on the research of generalize diagonal dominant matrices, we modify some conditions about diagonal dominant matrices which had existed. As its application a new set of conditions for block diagonal dominant matrix are obtained.
