- Abstract
In order to get a simple discriminant method of H-matrix,the concept of Ostrowski diagonally dominant matrix was extended to generalized Ostrowski diagonally dominant matrix. Combined with some techniques of inequalities,a new criteria conditions for a matrix to be a nonsingular H-matrix was obtained. The obtained result improves the known corresponding results. At last a numerical example is I given for illustrating advantage of result.
