pressio4py: Projection-based Model Reduction for Scientific Computing

This package provides Python bindings for the projection-based model reduction C++ library Pressio (website). The goal of this project is to enable leading-edge projection-based model reduction for (large-scale) linear and nonlinear dynamical systems.

Install

You need a C++14-compliant compiler and then do:

export CXX=<path-to-your-C++-compiler>
pip install pressio4py

You can double check that everything worked fine by doing:

import pressio4py
print(pressio4py.__version__)

Running Demos/Tutorials

After installing the library, you can run the regression tests:

git clone --recursive git@github.com:Pressio/pressio4py.git
cd pressio4py
pytest -s

And you can check out the demos:

git clone --recursive git@github.com:Pressio/pressio4py.git
cd pressio4py/demos
python3 ./<demo-subdir-name>/main.py

Documentation

The documentation (in progress) can be found (here) with some demos already available.
