This session provides a quick overview of the graphical block diagram environment in Simulink^®. Topics of discussion include how you can simulate, study the behavior, and optimize the performance of your system. This presentation demonstrates how the environment enables you to capture multiple domains in your system, for example, multibody, fluid, thermal, electrical, and control and signal processing algorithms. This is further supported by the ability to integrate your existing MATLAB^® or C/C++ code.
