| Opis: | The rational Arnoldi algorithm is a popular method in scientific computing used to construct an orthonormal basis
of a rational Krylov space. Each basis vector is a rational
matrix function times the starting vector. Rational functions possess a partial fraction expansion which often allows to compute several basis vectors simultaneously. However, this parallelism may cause instability due to the orthogonalization of ill-conditioned bases. We present and
compare continuation strategies to minimize these effects. |
