How to Create a S-Function in MATLAB

Introduction to S-Function Creation

• The tutorial focuses on creating an S-function from a previously developed plant model and controller model in MATLAB.

• Viewers are encouraged to refer to earlier videos in the playlist for foundational knowledge on plant and controller models.

Steps for Generating an S-Function

• To generate the S-function, right-click on the specific subsystem of the model, navigate to "C/C++ Code," and select "Test Function Generation."

• After building, an S-function will be created that represents C code implementation within the MATLAB environment. Inputs must be copied from the original model into the input ports of this new block.

Connecting Inputs and Outputs

• Proper connections between inputs and outputs are essential for functionality; viewers should ensure all ports are correctly linked.

• The generated S-function can be simulated within MATLAB, allowing users to verify its behavior against the original model.
