摘要

研究得到了一类特殊矩阵谱条件数上界的估计

与现有文献中只讨论参数α>1时这类矩阵条件数界的不同

本文补充讨论了α≤1时条件数的上界

完善了相应文献对这类特殊矩阵条件数的估计.

Abstract

The upper bound of a special kind of condition number of matrix spectrum is researched and estimated. The research supplements the estimation of such condition number in corresponding literature.
