Of course, Simulink is much more than a simple tool for solving differential equations. It has a richness and depth that will give me plenty of material to draw on. What kind of topics can you expect to read about here? We'll talk about applications of Simulink in controls, signal processing and communications system design. With your help, we'll talk about how Simulink is used in areas I don't even know about yet. We'll talk about Model-Based Design in general, and we'll get a peek at some of the internal machinery of Simulink.
