Simulink, developed by MathWorks, is a commercial tool for modeling, simulating and analyzing multidomain dynamic systems. Its primary interface is a graphical block diagramming tool and a customizable set of block libraries. In this book you will be able to learn the block diagrams techniques through step by step tutorial. This text includes the following chapters: Building a Model, Creating Subsystems, Solving Equations, Modeling with Control Flow Blocks, Creating Masked Subsystems, Solvers, Simulink Response Optimization, Lookup Tables, Complex Numbers, Model Construction Commands, SimMechanics, and Logic Circuit.
