Toeplitz matrices occur in many mathematical as well as scientific and engineering investigations. This paper considers the spectra of banded Toeplitz and quasi-Toeplitz matrices with emphasis on non-normal matrices of arbitrarily large order and relatively small bandwidth. These are the type of matrices that appear in the investigation of stability and(More)
Historically, the development and analysis of methods for ordinary differential equations (ODEs) have been more advanced than those for partial differential equations (PDEs). The present state of numerical methods is no exception; therefore, it behooves the numerical analyst to exploit sophisticated ODE methods for the numerical solution of PDEs.
