非奇异H-矩阵的新细分迭代判定
New Subdividing and Iterative Criteria for Nonsingular H-Matrices
摘要
Abstract
The concepts and properties of generalized α-diagonal dominant matrices,irreducible α-diagonal dominant matrices and α-diagonal dominant matrices with a nonzero elements chain are used to construct the progressive iteration coefficients by subdividing the index set of non-diagonal dominant rows,a set of practical nonsingular H-matrix subdivision iterative new criteria are obtained.Numerical examples illustrate the effectiveness of the new criteria.关键词
