Program Name: 
------------
GO+UTD (Geometrical Optics and Uniform Theory of Diffraction Toolbox)

Program Desription: 
-------------------
A MATLAB-based tool (GO+UTD) with a user-friendly graphical user interface (GUI) for the simulation of electromagnetic wave propagation and diffraction effects over variable terrain by using the geometrical optics (GO) and the uniform theory of diffraction (UTD) techniques. 


Program Development:
-------------------
The program has been developed in MATLAB version R2015b, and tested on Windows 10.

Installation: 
-------------
1. Install MATLAB (http://www.mathworks.com/) version R2015b or higher on your system to run the program. Note that “Parallel Computing Toolbox " are REQUIRED to run the program.
2. Extract the file "GOUTD.rar" to your hard disk.
3. Run MATLAB software and choose the folder you have initially extracted GOUTD. 
4. To run GOUTD, type "goutd" in the MATLAB command window, or open goutd.m with MATLAB editor and press F5.
5. The "Main Window" of the program will appear.
6. Enter the input parameters and click "Run" button to start the analysis.

Note that at the first run of the program, it takes extra time to start the parallel pool (parpool) of the MATLAB, which is performed once in the beginning.

***** Please Read the Paper First Before Using the Program *****

Example Files:
--------------
There are 9 example files in the "user_files" directory. The simulation results of these examples are shown in the paper.
In order to simulate these test cases, click the "Load", 
and select a file from the modal dialog box. 
The input parameters of the chosen example will be automatically loaded into appropriate boxes. 
Click the "Run" button to see the results.

Important Remark: 
-----------------
The names of the directories ("user_files" directory and its sub-directories) must not be changed at all.
