Stateflow

Working with Graphical Functions

A graphical function is a function defined by a flow graph. Graphical functions are similar to textual functions, such as MATLAB and C functions. Like textual functions, graphical functions can accept arguments and return results. You invoke graphical functions in transition and state actions in the same way you invoke MATLAB and C functions. Unlike C and MATLAB functions, however, graphical functions are full-fledged Stateflow objects. You use the Stateflow editor to create them and they reside in your Stateflow model along with the diagrams that invoke them. This makes graphical functions easier to create, access, and manage than textual functions, whose creation requires external tools and whose definitions reside separately from the model.
