AppendixMATLAB Functions List

The following is a list of all the MATLAB sources that are applied to generate the figures presenting the simulation results in this book. All MATLAB sources have been tested with MATLAB 2016B. If you are using MATLAB in other versions, beware that you may need to modify the sources, as MATLAB do update the language from time to time.
