Understanding Model Changes in MATLAB

Introduction to the Tutorial

• The tutorial focuses on how changes in a model impact the generated code, emphasizing code reusability and function types.

• Previous tutorials covered creating plant models, controller models, test harnesses, and understanding callbacks on model properties.

Modifying the Model

• The presenter demonstrates modifying an existing state flow chart by creating a group subchart for the "on State," which contains multiple substates.

• A subsystem is created within the model hierarchy, similar to Simulink's functionality.

Changing Function Properties

• The working state is changed from inline to function type through its properties menu.

• After building the model and generating C code, a new function named "working" appears in the output file due to this property change.

Observing Code Generation Effects

• The presenter shows how to locate the newly created function definition in the generated C code.

• By reverting back to inline settings for the working block, it’s demonstrated that no separate function will be created upon regeneration of C code.

Conclusion and Engagement

• This section highlights how controlling function creation can be achieved by adjusting model properties according to specific requirements.
