  • Aiming at the problem of fewer practical decision condition whether a matrix is nonsingular H-matrix, based on the properties of matrix element itself,by constructing positive diagonal matrix and comprehensive utilization of inequality techniques and sufficient and necessary conditions of nonsingular H-matrix,some of the judgement theorem were expanded and improved.And the scope of judging nonsingular matrices was also expanded.The numerical example showed that the new criterion had wide range of application than the original results.
