ONE TYPE OF NEW CRITERIA CONDITIONS FOR NONSINGULAR H-MATRICES
一类非奇异H-矩阵判定的新条件

Nonsingular H-matrices play a very important role in many fields,but it is difficult to determine a nonsingular H-matrix in practice.In this paper,we gave one type of new criteria conditions for nonsingular H-matrices,and improve some relate results.Advantages are illustrated by numerical examples.
