A note on the backward error analysis for eigenvalue problems 關(guān)于矩陣特征值問題向后誤差分析的注記
Backward error analysis of a class of the periodic symplectic matrices for eigenproblem 一類周期辛矩陣對特征值問題的向后誤差分析
In addition , the backward error for eigenvalue and eigenvector are analyzed respectively 此外還單獨考慮了對特征值和對特征向量的結(jié)構(gòu)向后誤差和向后誤差。
The optimal backward error and the condition number are important measures to evaluate the quality of computed solution 最佳向后誤差和條件數(shù)都是衡量計算解質(zhì)量的重要指標。
The expression or evaluation to the optimal structure backward error are given , compared with the result of optimal backward error 在有結(jié)構(gòu)要求時得出了特征對的結(jié)構(gòu)向后誤差的表達式或估計式,并與無結(jié)構(gòu)要求下的結(jié)果作了比較。
