Stateflow Programmatic Interface

Create and modify chart elements at the MATLAB^® command prompt

Programmatically create, edit, and simulate your Stateflow^® charts by using MATLAB commands. Access and edit the properties and methods, set positions, or copy and paste objects in your chart. Edit graphical properties by accessing the editor object.

Topics

Overview of the Stateflow API

Create and edit Stateflow charts by using MATLAB commands.

Create and Destroy Stateflow Objects

Add and delete Stateflow objects to your chart.

Access Objects in Your Stateflow Chart

Create handles to manipulate Stateflow objects in your chart.

Copy and Paste Stateflow Objects

Access the clipboard object to duplicate Stateflow objects.

View Stateflow Graphical Objects

Use the fitToView method to zoom in on an object in your chart.

Move Stateflow Graphical Objects

Programmatically reposition states and subcharts.

Modify the Graphical Properties of Your Chart

Access the Editor object to perform graphical operations on a chart.

Create Default Transition Objects

Indicate which substate becomes active during state initialization.

Create Supertransition Objects

Connect transitions between different levels in a chart.

Specify Labels in States and Transitions Programmatically

Specify more than one line of text in your state and transition labels.

Featured Examples

Create Charts by Using the Stateflow API

Create a Stateflow® chart by using the Stateflow application programming interface (API). The Stateflow API is a tool to create or change Stateflow charts through MATLAB® commands. For more information, see Overview of the Stateflow API.

Open Live Script

Create Charts by Using a MATLAB Script

Include Stateflow® API commands in a MATLAB® function or script. Creating a script of API commands allows you to avoid repetitive chart creation steps and recreate the same model with a single command. For more information, see Overview of the Stateflow API.
