摘要:

文献中已对结构矩阵在一般或结构扰动下的特征值敏感性进行了深入研究。误差界可用,并可通过伪谱计算来获得洞察。很少有研究关注一般或结构扰动下特征向量的敏感性分析。本文讨论了三对角Toeplitz和Toeplitz型矩阵的这种敏感性。

英文摘要:

The sensitivity of eigenvalues of structured matrices under general or structured perturbations of the matrix entries has been thoroughly studied in the literature. Error bounds are available and the pseudospectrum can be computed to gain insight. Few investigations have focused on analyzing the sensitivity of eigenvectors under general or structured perturbations. The present paper discusses this sensitivity for tridiagonal Toeplitz and Toeplitz-type matrices.
