Stateflow

What Is Stateflow?

Stateflow is a graphical design and development tool for control and supervisory logic used in conjunction with Simulink. Using Stateflow you can

• Visually model and simulate complex reactive systems based on finite state machine theory
• Design and develop deterministic, supervisory control systems
• Easily modify your design, evaluate the results, and verify the system's behavior at any stage of your design
• Automatically generate integer, floating-point, or fixed-point code directly from your design (requires Stateflow Coder)
• Take advantage of the integration with the MATLAB and Simulink environments to model, simulate, and analyze your system

Stateflow provides clear, concise descriptions of complex system behavior using finite state machine theory, flow diagram notations, and state-transition diagrams all in the same Stateflow diagram. Stateflow brings system specification and design closer together. It is easy to create designs, consider various scenarios, and iterate until the Stateflow diagram models the desired behavior.

Flow diagram notation creates decision-making logic such as for loops and if-then-else constructs without the use of states. In some cases, using flow diagram notation provides a closer representation of the required system logic that avoids the use of unnecessary states.
