What is Simulink?  It is a simulation tools developed by MathWorks.  This tool is used for modeling, simulating and analyzing dynamic systems.  Its primary interface is a graphical block diagramming tool.  This tool is tightly integrated with rest of the Matlab environment.

Key Features  Graphical editor for building and managing hierarchical block diagrams  Libraries of predefined blocks for modeling continuous-time and discrete-time systems  Simulation engine with fixed-step and variable-step ODE solvers  Scopes and data displays for viewing simulation results  Project and data management tools for managing model files and data  Model analysis tools for refining model architecture and increasing simulation speed  MATLAB Function block for importing MATLAB algorithms into models  Legacy Code Tool for importing C and C++ code into models.

System Modeling

What is Purpose? To give the basics for simulating different models using Simulink. Consequently, common and many default settings for blocks will be used. For more detailed features students must refer to Matlab for the considered blocks.

Examples Source Sink Scope window — If a Scope window is closed at the start of a simulation, scope data is still written to the connected Scope. As a result, if you open a Scope after a simulation, the Scope window displays the input signal or signals.

Examples Vector that defines two sine signals Sine Cosine

Examples On the Scope window toolbar, click the Parameters button The values you entered or selected apply to the next simulation.

Examples To add signals to a Floating Scope, click the Signal Selector button, and then select signals from your model. For more information, see Signal Selector.

Examples Displaying X-Y plot of signals using MATLAB figure window
