Implement Algorithms Using C/C++ Code
Implement C/C++ code in Simulink® using the blocks you develop. You can use these methods to implement your code:
C Caller Block — Integrates C code into Simulink by importing your C functions.
C Function Block — Integrates and calls external C code from a Simulink model
S-Function — Uses special syntax called S-function API to communicate with the Simulink engine. They allow you to create continuous, discrete, and hybrid systems.
S-Function Builder — Integrates C/C++ code by building an S-function from your code with the specifications you supply. The S-function builder also serves as a wrapper for the S-functions generated in your models.
Legacy Code Tool — Integrates C/C++ functions, such as lookup tables, and general functions and interfaces into Simulink models.
Use the C Caller block to call a C function to your model that has no states. To create an S-function without states, use Legacy Code Tool. If you would like to work with states and methods, use the S-function Builder or S-functions.
