Stateflow User's Guide

Using Actions in Stateflow

Stateflow attaches actions to a state or transition through its label. The actions in action language can be broadcast events, condition statements, function calls, variable assignments and operations, and so on. Many are very similar to statements in C or MATLAB. Stateflow also defines categories for the actions that you specify, known as action types. This chapter describes the action types of states and transitions and the actions that they contain in the following sections:

Defining Action Types	Gives a description of each type of action language available to states and transitions and shows their behavior in an example.
Using Operations in Actions	Describes the available data operations in Stateflow action language.
Using Special Symbols in Actions	Learn the special symbols Stateflow uses to provide the user with special features in action language notation.
Calling C Functions in Actions	Describes the C functions that you can call directly in Stateflow action language.
Using MATLAB Functions and Data in Actions	Tells you how you can call MATLAB functions and access MATLAB workspace variables in action language, using the `ml` namespace operator or the `ml` function.
Using Data and Event Arguments in Actions	Tells you how to reference data defined at different levels of containment in a Stateflow chart when you use them as arguments for functions that you call in action language.
Using Arrays in Actions	Describes how to use Stateflow data arrays in action language.
Broadcasting Events in Actions	Describes event broadcasting and directed event broadcasting in action language.
Using Temporal Logic in Actions	You can test the occurrence of a specified multiple of events. Learn how to use temporal logic in Stateflow action language.
Using Bind Actions to Control Function-Call Subsystems	Gives a quick example of each type of action language available to Stateflow.
