Efficient space–time reduced order model for linear dynamical systems in python using less than 120 lines of code
A classical reduced order model (ROM) for dynamical problems typically involves only the
spatial reduction of a given problem. Recently, a novel space–time ROM for linear …

Data-driven model order reduction of linear switched systems in the Loewner framework
The Loewner framework for model reduction is extended to the class of linear switched
systems. One advantage of this framework is that it introduces a trade-off between accuracy …
