The Simulink model window contains menu items we have not discussed. However, the oiles we have discussed are the most important ones for getting started. We have introduced just a-few of the blocks available within Simulink. Some of the blocks not discussed deal with discrete-time systems (ones modeled with difference,
rather than differential, equations), digital logic systems, and other types of mathematical operations. In addition, some blocks have additional properties that we have not mentioned. However, the examples given here will help you get started in explonhg the other features of Simulink. Consult the online help for information about these items.
