The scripts "test_heat_LTI.py", "test_synthetic_tf_MIMO.py" and "test_synthetic_tf_SISO.py" showcase different examples.
Python version 3.7 or higher should be used. The necessary packages are listed in requirements.txt and can be installed, e.g. via running
pip install -r requirements.txt
in the installation folder.
