StateFlow is a toolbox from MathWorks for development of state machines

Stateflow is an toolbox (extension) of Matlab from Mathworks. It is a commercial, and proprietary toolset.

Generally, Stateflow extends Simulink with the ability to design and test state machines. It is commonly used in control design, where algorithms can be either matlab scripts & formulas, simulink blocks or embedded code (in the form of so-called S-functions).

Code generation is supported on the host platform, but for target code additional tools are required (such as real time Workshop).

Advantages compared to software-only tooling (like IBM Rhapsody):

  • use with hardware (in the loop)
  • seemless integration with Simulink

Disadvantages compared to software-only tooling:

  • cost for code generation

Visualizing a Stateflow Model

I have a pretty simple MATLAB stateflow model that I would like to visualize. I don't need anything fancy - even if I could just display a different image based on which substate a parallel state is in. Does anyone have any suggestions about what I…

Simulink Stateflow - 'after' condition not precise?

I implemented an integrator (grounded capacitor driven by piece-wise constant current source) using Stateflow and the 'after' condition. See code. With the given setting the capacitor should change its voltage every 1 sec, but does so about every…

Copy stateflow in a Simulink model

I would like to copy a Stateflow chart The command: Simulink.SubSystem.copyContentsToBlockDiagram(subsys, bdiag) doesn't work on a Stateflow chart alone, rather then only on subsystems. How could I copy a selected Stateflow to another system?
