Numerical Examples for Structured $\mathcal{H}_2$-optimality Conditions

This repository contains code for numerical experiments reported in

P. Mlinarić, P. Benner, S. Gugercin, Interpolatory $\mathcal{H}_2$-optimality Conditions for Structured Linear Time-invariant Systems, arXiv preprint, 2023

Installation

The code is implemented in the Python programming language (tested using Python 3.10.12).

The necessary packages are listed in requirements.txt. They can be installed in a virtual environment by, e.g.,

python3 -m venv .venv
source .venv/bin/activate
pip install -U pip
pip install -r requirements.txt

Running the Experiments

The experiments are given as three Python scripts (second-order.py, port-Hamiltonian.py, time-delay.py). Note that second-order.py and port-Hamiltonian.py may complete in a few minutes, but time-delay.py may take 10h.

The scripts can be opened as Jupyter notebooks via jupytext.
