EPANET-MATLAB-Toolkit (EMT)
The EPANET-Matlab Toolkit is an open-source software, originally developed by the KIOS Research and Innovation Center of Excellence, University of Cyprus which operates within the Matlab environment, for providing a programming interface for the latest version of EPANET, a hydraulic and quality modeling software created by the US EPA, with Matlab, a high-level technical computing software. The goal of the EPANET Matlab Toolkit is to serve as a common programming framework for research and development in the growing field of smart water networks.
The EPANET-Matlab Toolkit features easy to use commands/wrappers for viewing, modifying, simulating and plotting results produced by the EPANET libraries.

How to install necessary compilers
In order to use the EPANET-MATLAB-Toolkit the MinGW-w64 compiler must be install:
<img src="http://img.youtube.com/vi/R_RABL3_6EY/0.jpg" alt="How to install MinGW-w64 compiler #Matlab" width="240" height="180" border="5" />
In case you have a version of matlab older than 2015b install the Windows SDK compiler :

How to use the Toolkit
Detailed examples on how to use the toolkit can be found in the publication of the Toolkit , together with the code. A presentation of its use is also provided here.
To start, you need to download the folder from GitHub (e.g., Download ZIP), set the run path in Matlab within the saved folder, and run RunTests.m. This will execute all the commands which have been implemented in the Class.
Minimum Example:
d=epanet('Net1.inp')
d.getNodeCount
d.getNodeElevations
Help Functions:
help d.plot
How to fix/report bugs
To fix a bug Fork the EPANET-Matlab Toolkit, Edit the code and make the appropriate change, and then Pull it so that we evaluate it.
Keep in mind that some bugs may exist in the EPANET libraries, in case you are not receiving the expected results.
