Ym. Gao et Xh. Wang, CRITERIA FOR GENERALIZED DIAGONALLY DOMINANT MATRICES AND M-MATRICES .2., Linear algebra and its applications, 248, 1996, pp. 339-353
We provide new necessary and sufficient conditions for verifying (stri
ctly) generalized diagonally dominant matrices by applying the inverse
of a partitioned matrix and obtain some criteria for identifying (non
singular) M-matrices.
