Computational graphs for matrix functions
Elias Jarlebring, Massimiliano Fasi, Emil Ringh
Many numerical methods for evaluating matrix functions can be naturally viewed as computational graphs. Rephrasing these methods as directed acyclic graphs (DAGs) is a particularly…
Nonlinearizing two-parameter eigenvalue problems
Emil Ringh, Elias Jarlebring
We investigate a technique to transform a linear two-parameter eigenvalue problem, into a nonlinear eigenvalue problem (NEP). The transformation stems from an elimination of one of…
NEP-PACK: A Julia package for nonlinear eigenproblems - v0.2
Elias Jarlebring, Max Bennedich, Giampaolo Mele +2
We present NEP-PACK a novel open-source library for the solution of nonlinear eigenvalue problems (NEPs). The package provides a framework to represent NEPs, as well as efficient i…
Residual-based iterations for the generalized Lyapunov equation
Tobias Breiten, Emil Ringh
This paper treats iterative solution methods to the generalized Lyapunov equation. Specifically it expands the existing theoretical justification for the alternating linear scheme…
Krylov methods for low-rank commuting generalized Sylvester equations
Elias Jarlebring, Giampaolo Mele, Davide Palitta +1
We consider generalizations of the Sylvester matrix equation, consisting of the sum of a Sylvester operator and a linear operator with a particular structure. More precisely, t…
Sylvester-based preconditioning for the waveguide eigenvalue problem
Emil Ringh, Giampaolo Mele, Johan Karlsson +1
We consider a nonlinear eigenvalue problem (NEP) arising from absorbing boundary conditions in the study of a partial differential equation (PDE) describing a waveguide. We propose…
Time Localization and Capacity of Faster-Than-Nyquist Signaling
Ather Gattami, Emil Ringh, Johan Karlsson
In this paper, we consider communication over the bandwidth limited analog white Gaussian noise channel using non-orthogonal pulses. In particular, we consider non-orthogonal trans…
