Abstract:

Based on the concept of diagonally dominant matrices, several new sufficient conditions to determine nonsingular Hmat
rices are given and thus the corresponding results are improved and generalized in this paper. A numerical example is given to show the advantages of our results.

Key words: diagonlly dominant matrices; nonzero elements chain; positive diagonally matrices
