RATIONAL KRYLOV FOR REAL PENCILS WITH COMPLEX EIGENVALUES
RATIONAL KRYLOV FOR REAL PENCILS WITH COMPLEX EIGENVALUES
A rational Krylov algorithm for eigenvalue computation is described. It is usable on a real matrix pencil with complex eigenvalues and builds up a real basis. The main purpose is to get real reduced models of a real linear dynamic system. Two variants are described, one where two real vectors …
