,Preface
Simulink, developed by The MathWorks, is a commercial tool for modeling, simulating and analyzing
dynamic systems. Its primary interface is a graphical block diagramming tool and a customizable set
of block libraries. It offers tight integration with the rest of the MATLAB environment and can either
drive MATLAB or be scripted from it. Simulink is widely used in control theory and digital signal
processing for simulation and design.
This training will give you the basic knowledge of Simulink and how you can use it together with
MATLAB.
