A note on the backward error analysis for eigenvalue problems 关于矩阵特征值问题向后误差分析的注记
Backward error analysis of a class of the periodic symplectic matrices for eigenproblem 一类周期辛矩阵对特征值问题的向后误差分析
In addition , the backward error for eigenvalue and eigenvector are analyzed respectively 此外还单独考虑了对特征值和对特征向量的结构向后误差和向后误差。
The optimal backward error and the condition number are important measures to evaluate the quality of computed solution 最佳向后误差和条件数都是衡量计算解质量的重要指标。
The expression or evaluation to the optimal structure backward error are given , compared with the result of optimal backward error 在有结构要求时得出了特征对的结构向后误差的表达式或估计式,并与无结构要求下的结果作了比较。
