摘要
给出了几个新的判定复方阵为广义对角占优矩阵和复方阵的比较矩阵为非奇M-矩阵的充分条件.同时,也得到了非广义对角占优矩阵的判定方法.
This paper gives sufficient conditions for determining a complex square matrix to be a generalized diagonally dominant matrix and a complex square matrix's comparative matrix to be a nonsingular M-matrix. At the same time, a criteria method for non-generalized diagonal dominant matrices is given in this paper.
