Real-Time Workshop

The S-Function Target

S-functions are an important class of target for which Real-Time Workshop can generate code. The ability to encapsulate a subsystem into an S-function allows you to increase its execution efficiency and shield its internal logic from inspection and modification. Here we describe the properties of S-function targets and demonstrate how to generate them. For further details on the structure of S-functions, see Writing S-Functions in the Simulink documentation.
