非奇异H-矩阵判定的迭代准则
New iterative codes for nonsingular H - matrices
摘要
Abstract
Nonsingular H - matrices play a very important role in numerical analysis, matrix theory, mathematical economics,etc. But it is difficult to determine a nonsingular H - matrix in practice. In this paper, we gave several new sufficient conditions for nonsingular H - matrices, improved and generalized some relate results. Advantage of the results obtained was illustrated by some numerical examples.关键词
