PEPQARNOLDI#
PEPQARNOLDI = “qarnoldi” - The Quadratic Arnoldi method (Q-Arnoldi) for quadratic eigenvalue problems.
Notes#
This solver is available for quadratic eigenproblems only.
It implements the Q-Arnoldi method [Meerbergen, 2009], which is not guaranteed
to be numerically stable. Users should prefer PEPTOAR, which
provides a similar algorithm with guaranteed numerical stability.
