stateflow

Open Stateflow template page

Syntax

stateflow

Description

stateflow opens the Stateflow^® section of the Simulink^® Start Page. In this section, you can select templates for several common chart types, including models that contain nested or parallel states.

This image shows the template list as it appears in the Simulink Start Page.

Examples

Open Simple Stateflow Chart Template

Use the Simple Stateflow Chart template to create a Stateflow chart with two states. For more information about designing a simple Stateflow chart, see Create Stateflow Charts.

Use the stateflow command to open the Stateflow section of the Simulink Start Page. Click Simple Stateflow Chart.

Open Heirarchical Chart Template

Use the Heirarchical Chart template to create a Stateflow chart with nested child states. For more information about parent and child states, see Create Parent and Child Operating Modes.

Use the stateflow command to open the Stateflow section of the Simulink Start Page. Click Heirarchical Chart.

Open Simple State Transition Table Template

Use the Simple State Transition Table template to create a state transition table with two states. For more information about state transition tables, see Model Finite State Machines Using State Transition Tables.

Use the stateflow command to open the Stateflow section of the Simulink Start Page. Click Simple State Transition Table.

Open Chart with Reusable Logic Template

Since R2025a

Use the Chart with Reusable Logic template to create a Stateflow chart that includes a MATLAB Function, a Simulink Function, and a graphical function. For more information about reusable logic, see Reuse MATLAB Code by Defining MATLAB Functions and Reuse Simulink Functions in Stateflow Charts.

Use the stateflow command to open the Stateflow section of the Simulink Start Page. Click Chart with Reusable Logic.

Open Chart with Parallel States Template

Since R2025a

Use the Chart with Parallel States template to create a Stateflow chart with two parallel states. For more information about parallel states, see Execute States in Parallel.

Use the stateflow command to open the Stateflow section of the Simulink Start Page. Click Chart with Parallel States.

Open Moore Chart Template

Use the Moore Chart template to create a Moore chart. A Moore chart is a Stateflow chart where the outputs do not depend on inputs, previous outputs, or temporal logic. For more information about Moore charts, see Overview of Mealy and Moore Machines.

Use the stateflow command to open the Stateflow section of the Simulink Start Page. Click Moore Chart.

Version History

Introduced before R2006a

R2025a: Updated templates in Simulink Start Page

To quickly set up a Stateflow charts or state transition table, use an updated template in the Simulink Start Page. Stateflow templates now include:

• Tips and links to the Get Started with Stateflow category

• Singal lines to Inport (Simulink) and Outport (Simulink) blocks in Simulink

The Start Page also contains these new templates:

• Chart with Reuseable Logic

• Chart with Parallel States

R2024a: Creating models and opening block library no longer supported

The stateflow function opens the Simulink template page for Stateflow instead of creating an untitled Simulink model and opening the Stateflow block library.

To create a model that contains an empty chart block, use the sfnew function. To open the Stateflow block library, use the sflib function.

R2019b: Creating models and opening block library will no longer be supported

The stateflow function creates an untitled Simulink model that contains an empty Stateflow chart and opens the Stateflow block library without error.
