| Abstract: | Generalized diagonally dominant matrices play a very important role in numerical analysis,matrix theory,mathematical economics,etc.However,it is difficult to make a criteria for them in practice.This paper studies the criteria for generalized diagonally dominant matrices.Some new sufficient conditions are obtained and some related results are improved.A numerical example illustrates the advantages. |
