The EPANET-Matlab Toolkit is an open-source software initially developed in Matlab, providing a programming interface for the latest version of hydraulic and quality modeling software developed jointly by the US EPA and Matlab. This toolkit serves as a general programming framework for research and development in the growing field of intelligent water networks, offering easy-to-use commands and wrappers for viewing, modifying, simulating, and plotting results generated by the EPANET library.
