非奇异H-矩阵的一组新判据
A New Set of Criteria for Nonsingular H-Matrices
摘要
Abstract
Based on the generalized strictly α-diagonally dominant matrices and its related concepts and properties,by dividing the matrix index set,forming corresponding positive diagonal factors and setting new parameters,we gave a set of practical new criteria for nonsingular H-matrices,expanding the judgment range of nonsingular H-matrices.Finally,numerical examples were used to illustrate the effectiveness of the new criterion.关键词
