Writing S-Functions

Chapter 1
Overview of S-Functions

S-functions (system-functions) provide a powerful mechanism for extending the capabilities of Simulink^®. The following sections explain what an S-function is and when and why you might use one and how to write your own S-functions.


What Is an S-Function?	Brief overview of S-functions.
Using S-Functions in Models	How to insert S-functions as blocks in a model and pass parameters to them.
How S-Functions Work	How Simulink invokes S-functions when simulating a model that includes them.
Implementing S-Functions	How to write S-functions.
S-Function Concepts	Some key concepts needed to write certain types of S-functions.
S-Function Examples	Examples that illustrate the creation of various types of S-functions and S-function features.
