removeHighlighting

Remove highlighting of active states

Syntax

removeHighlighting(op)

Description

removeHighlighting(op) removes the highlighting of active states in the Stateflow^® Editor.

Examples

Modify Operating Point Information for State Activity

1. Open the sf_car model.

   openExample("sf_car")

   For more information about this model, see Model a Car with Automatic Transmission.

2. Set the model to save the final operating point. Open the Configuration Parameters dialog box and, in the Data Import/Export pane:

   1. Select Final states and enter a name for the operating point. For this example, use xSteadyState.

   2. Select Save final operating point.

   3. Click OK.

3. Set the stop time for this simulation segment. In the Simulation tab, set Stop Time to 3.

4. Run the simulation.

5. Access the Stateflow.op.BlockOperatingPoint object that contains the operating point information for the shift_logic chart.

   blockpath = "sf_car/shift_logic";
   op = get(xSteadyState,blockpath)

   op = 
   
   Block: "shift_logic"    (handle)    (active)
     Path:     sf_car/shift_logic
   
     Contains:
   
       + gear_state                     "State (AND)"                        (active)       
       + selection_state                "State (AND)"                        (active)       
         gear                           "State output data"                  gearType [1, 1]
         down_th                        "Local data"                         double [1, 1]  
         up_th                          "Local data"                         double [1, 1]  
         datasetWrittenToVector         "Data set written to vector"         logical 4x1  

6. Access the Stateflow.op.OperatingPointContainer object that contains the operating point information for the gear_state state.

   op.gear_state

   ans = 
   
   State: "gear_state"    (handle)    (active)
     Path:     sf_car/shift_logic/gear_state
   
     Contains:
   
       + first          "State (OR)"         (active)
       + fourth         "State (OR)"                 
       + second         "State (OR)"                 
       + third          "State (OR)"

7. Highlight the states that are active in the chart at t = 3.

   highlightActiveStates(op)

   

8. Change the substate activity in the state gear_state to reflect a change in gear.

   setActive(op.gear_state.second)

   

9. Verify that the substate second in the state gear_state is active in the modified operating point.

   isActive(op.gear_state.second)

   ans =
   
     logical
   
      1

10. Remove the highlighting of active states in the Stateflow Editor.

    removeHighlighting(op)

Input Arguments

op — Operating point for chart

Stateflow.op.BlockOperatingPoint object

Operating point for a Stateflow chart, specified as a Stateflow.op.BlockOperatingPoint object.
