Model reduction for second-order systems with inhomogeneous initial conditions
Jennifer Przybilla, Igor Pontes Duff, Peter Benner
In this paper, we consider the problem of finding surrogate models for large-scale second-order linear time-invariant systems with inhomogeneous initial conditions. For this class…
