Title: | A symmetry exploiting Lanczos method for symmetric Toeplitz matrices | Language: | English | Authors: | Voß, Heinrich | Keywords: | Toeplitz matrix; eigenvalue problem; Lanczos method; symmetry | Issue Date: | Jul-1999 | Abstract (english): | Several methods for computing the smallest eigenvalues of a symmetric and positive definite Toeplitz matrix T have been studied in the literature. The most of them share the disadvantage that they do not reflect symmetry properties of the corresponding eigenvector. In this note we present a Lanczos method which approximates simultaneously the odd and the even spectrum of T at the same cost as the classical Lanczos approach. |
