In a Stateflow chart, a Simulink function is a graphical object that you fill with Simulink blocks and call in the actions of states and transitions. This function provides an efficient model design and improves readability by minimizing graphical and nongraphical objects. Typical applications include:
Defining a function that requires Simulink blocks, such as lookup tables (see About Lookup Table Blocks in the Simulink documentation)
Scheduling execution of multiple controllers
