非奇异H-矩阵的新判据
New conditions for nonsingular H-matrix
摘要
Abstract
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 com-prehensive utilization of inequality techniques and sufficient and necessary conditions of nonsingular H-ma-trix,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 appli-cation than the original results.关键词
