An operating point is a snapshot of the state of a Simulink® model at a specific time during simulation. For a Stateflow® chart, an operating point includes:
Activity of chart states
Values of chart local data
Values of chart output data
Values of persistent data in MATLAB® functions and Truth Table blocks
For more information, see Using Operating Points in Stateflow.
You can use the following methods to interact with the operating point of a chart. Assume
that ch is a handle to the operating point of your chart, which you obtain
using the get
method.
| Type of Object | Method | Description | Example |
|---|---|---|---|
All chart objects | open | For graphical objects, highlights the object in the Stateflow Editor. For nongraphical objects, highlights the object in the Model Explorer. Note For persistent data in MATLAB functions, this method opens the function editor and highlights the persistent data at the exact line in the script. | ch.data.open |
Chart | checkStateConsistency | Verifies that all states in a chart are consistent.
| ch.checkStateConsistency |
Chart | clone | Copies the entire chart operating point to a new variable. | newOperatingPoint =
ch.clone |
Chart | highlightActiveStates | Highlights all active states in the Stateflow Editor. | ch.highlightActiveStates |
Chart | isStateConsistent | Returns true (1) if all states pass a consistency check and false (0) otherwise. | ch.isStateConsistent |
Chart | removeHighlighting | Removes all highlighting in the Stateflow Editor. | ch.removeHighlighting |
State | isActive | Returns true (1) if a state is active and false (0) otherwise. | ch.state.isActive |
State Must be an exclusive leaf state | setActive | Sets a state to be active. This method ensures that no other exclusive states at that level are active. | ch.state.substate.setActive |
State Must have a history junction and exclusive substates | getPrevActiveChild | Returns the previously active substate. | ch.state.getPrevActiveChild |
State Must be inactive; must have a history junction and exclusive substates | setPrevActiveChild | Sets the previously active substate. |
Note The argument must be the name of a substate (in quotes), or the full operating point path to a substate (without quotes). |
