Structural Controllability Algorithms

This resource contains the MATLAB codes and data files needed to replicate the results presented in \"M. S. Riasi, L. Yeghiazarian, Controllability of Surface Water Networks, Water Resources Research, 2017.\"
Theis resource contains two separate packages:

1. Controllability CODE: This folder contains the MATLAB scripts and data needed to perform structural controllability analysis. User can run the code simply by running the \"MAIN.m\" script. Immediately after running this script, user is prompted to select a text file that contains the directed graph of the network from \"Input Data\" folder. \"Input Data\" folder includes the digraphs of all 11 networks used in this study. For each network, two .txt file exist: \"NetworkName.txt\" and \"NetworkName_XY\". The first text file includes the edges of the the digraph and the latter includes coordinate of the nodes. For the MAIN script to work, user must select the \"NetworkName.txt\".

2. Network Extraction: The network extraction code only consists of one MATLAB script: \"StreamNetReader.m\". This script was written to extract the digraph of delta images. By running \"StreamNetReader.m\", user can select from a catalog of 7 delta images.
