DZ-Type-QN矩阵逆的无穷大范数的上界
Upper bounds for the infinity norm of the inverse of DZ-Type-QN matrices
摘要
Abstract
This paper proposes a new subclass of H-matrices called DZ-Type-QN matrices and presents their some properties.The relations between DZ-Type-QN matrices and other subclasses of H-matrices are considered.Based on the characteristics H-matrices,the infinity norm bounds of the inverse involving DZ-Type-QN matrices are established,which improve some existing results.The effectiveness of the new results is illustrated by some numerical examples.关键词
