When is a matrix unitary or Hermitian plus low rank?
Gianna M. Del Corso, Federico Poloni, Leonardo Robol +1
Hermitian and unitary matrices are two representatives of the class of normal matrices whose full eigenvalue decomposition can be stably computed in quadratic computing com plexity…
Biorthogonal Extended Krylov Subspace Methods
Niel Van Buggenhout, Marc Van Barel, Raf Vandebril
A general framework for oblique projections of nonhermitian matrices onto rational Krylov subspaces is developed. To obtain this framework we revisit the classical rational Krylov…
A rational QZ method
Daan Camps, Karl Meerbergen, Raf Vandebril
We propose a rational QZ method for the solution of the dense, unsymmetric generalized eigenvalue problem. This generalization of the classical QZ method operates implicitly on a H…
