Abstract
We present a review of the main specialized techniques for finding the eigenvalues of a Toeplitz matrix, based on fast evaluation of the characteristic polynomial, restricted rank projection methods or updating procedures. The latter approach is described in more detail, by presenting some recent extensions to rational Toeplitz matrices and to the computation of (generalized) Toeplitz singular values, which can be of great interest in image processing applications.
