摘要
非奇H矩阵在众多领域有着重要的应用,但其判别却很困难.本文给出了非奇异H-矩阵若干个新的判据.推广了近期的相应结果.
Nonsingular H-matrices play an important role in many fields, but in pratice it is difficult to determine whether a matrix is an nonsingular H-matrix or not. In this paper, we gave some new conditions for nonsingular H-matrices. Improved and generalized some relate result.
