Riccati ADI: Existence, uniqueness and new iterative methods
Christian Bertram, Heike Faßbender
The approximate solution of large-scale algebraic Riccati equations is considered. We are interested in approximate solutions which yield a Riccati residual matrix of a particular…

A link between gramian based model order reduction and moment matching
Christian Bertram, Heike Faßbender
We analyze a family of Runge-Kutta based quadrature algorithms for the approximation of the gramians of linear time invariant dynamical systems. The approximated gramians are used…
