abstract = {The class of generalized    S  D            D      1              (          G      S      D                        D          1                      )   matrices is a new subclass of    H-matrices. In this paper, we focus on the subdirect sum of    G  S  D            D      1       matrices, and some sufficient conditions to ensure that the subdirect sum of    G  S  D            D      1       matrices with strictly diagonally dominant        (          S      D      D        )   matrices is in the class of    G  S  D            D      1       matrices are given. Moreover, corresponding examples are given to illustrate our results.}
