If you have found Matpower to be valuable, please consider supporting the project by becoming a sponsor at https://matpower.org/sponsor.
As a free, open-source tool, Matpower development relies on research grants and contracts as well as support from sponsors and donors. The software is and always has been provided free of charge under an open-source license, but its development and support require significant resources. Any contributions from the community or other sponsors free us to focus on that support and the development of valuable new features.
