S-Function Callback Methods — Alphabetical List

---

Every user-written S-function must implement a set of methods, called callback methods or simply callbacks, that the Simulink engine invokes when simulating a model that contains the S-function. Some callback methods are optional. The engine invokes an optional callback only if the S-function defines the callback. This section describes the purpose and syntax of all callback methods that an S-function can implement. In each case, the documentation for a callback method indicates whether it is required or optional. For a list of required callback methods, see Callback Methods That an S-Function Must Implement.
