A very rudimentary and simple implementation of the iteratively corrected rational Krylov algorithm for $H_2$ model reduction proposed by Gugercin, Antoulas and Beattie [GugercinAntoulasBeattie08]. Part of this work is inspired from the work of Heiko K.F. Panzer [Panzer14].
This implementation was made for the Paper BEST PRACTICES FOR NUMERICAL REPLICABILITY, REPRODUCIBILITY AND REUSABILITY EXEMPLIFIED BY MODEL REDUCTION SOFTWARE
This implementation either runs with Matlab or with Octave
- Dependencies
For MATLAB as well as octave the control toolbox needs to be available
- RunMe
1. change into installation directory 2. run TestIRKA.m
Octave version >=3.8 with control-package needs to be installed
- Installation
1. no installation is required
