Writing S-Functions

Writing S-Functions in C

The following sections explain how to use the C programming language to create S-functions.


Introduction	Overview of writing a C S-function.
Building S-Functions Automatically	How to use the S-Function Builder to generate S-functions automatically from specifications that you supply.
S-Function Builder Dialog Box	Describes the S-Function Builder dialog box
Example of a Basic C MEX S-Function	Illustrates the code needed to create a C S-function.
Templates for C S-Functions	Describes code templates that you can use as startingpoints for writing your own C S-functions.
How Simulink Interacts with C S-Functions	Describes how Simulink interacts with a C S-function. This is information that you need to know in order to create and debug your own C S-functions.
Writing Callback Methods	How to write methods that Simulink calls as it executes your S-function.
Converting Level 1 C MEX S-Functions to Level 2	How to convert S-functions written for earlier releases of Simulink to work with the current version.
