Simulink Functions

Create functions accessible in Simulink models

A Simulink® function is a computational unit that calculates a set of outputs when provided with a set of inputs. Since a Simulink function provides a common text interface to its function definition and a function caller, how you define the function is your choice. Possible function definitions include using:

  • Simulink blocks in a Simulink Function block

  • Stateflow® state transitions in an exported Stateflow graphical function

  • MATLAB® code statements in an exported Stateflow MATLAB function

After you define a function, you can call it using a Function Caller block, a MATLAB Function block, or a Stateflow chart.
