Fast Toeplitz eigenvalue computations, joining interpolation-extrapolation matrix-less algorithms and simple-loop theory

M. Bogoya, S. E. Ekström, S. Serra-Capizzano

Under appropriate technical assumptions, the simple-loop theory allows to deduce various types of asymptotic expansions for the eigenvalues of Toeplitz matrices generated by a func…

A Matrix-Less Method to Approximate the Spectrum and the Spectral Function of Toeplitz Matrices with Complex Eigenvalues

Sven-Erik Ekström, Paris Vassalos

It is known that the generating function $f$ of a sequence of Toeplitz matrices ${T_{n} (f)}_{n}$ may not describe the asymptotic distribution of the eigenvalues of $T_{n} (f)$ if $f$ is…
