Isospectral algorithms, Toeplitz matrices and orthogonal polynomials
… of isospectral algorithms, all pertaining to Toeplitz matrices in some fashion, and one directly involving orthogonal polynomials. The first set of algorithms we study come from discretising a continuous isospectral flow designed to converge to a symmetric Toeplitz matrix with prescribed …

High-performance algorithms to solve Toeplitz and block Toeplitz matrices
Fast algorithms to factor Toeplitz matrices have existed since the beginning of this century. The two most notable algorithms to factor Toeplitz matrices are the Schur and the Levinson-Durbin. The former factors the Toeolitz matrix itself while the latter factors the inverse. In this thesis, we …

Structured linear algebra problems and applications to system identification
… rank estimation and conditioning for structured matrices. The ideas are developed with attention to potential applications in control and signal processing where such matrices arise routinely. A stability result for the factorization of the broad class of positive definite Toeplitz-like matrices …

Multiphysics Design and Modeling for Advanced Packaging and Heterogeneous Integration of Power Delivery
… approach with Fourier series–based Toeplitz matrices. This method provides a unified framework for transient electrical simulations and steady-state thermo-mechanical analysis, representing time-varying system elements in the frequency domain to improve stability and efficiency. To …

Fast order-recursive Hermitian Toeplitz eigenspace techniques for array processing
… dissertation presents a fast Recursive/Iterative Toeplitz (Hermitian) Eigenspace (RITE) algorithm, and its extension to the generalized strongly regular eigendecomposition situation (C-RITE). Both procedures exhibit highly parallel structures, and their applicability to fast passive array …

Detection of multiple correlated time series and its application in synthetic aperture sonar imagery
… the true GLRT for this problem would impose a Toeplitz structure (more specifically, a Toeplitz-block-Toeplitz structure) on the estimate of the composite covariance matrix, an intractable problem with no closed-form solution, the asymptotic theory of large Toeplitz matrices shows that the …
