Writing S-Functions

Writing Callback Methods

Writing an S-function basically involves creating implementations of the callback functions that Simulink invokes during a simulation. For guidelines on implementing a particular callback, see the documentation for the callback in Chapter 9, S-Function Callback Methods. For information on using callbacks to implement specific block features, such as parameters or sample times, see Chapter 7, Implementing Block Features.
