get
Description
returns the value of the specified parameter Output
= get(ScenarioSim
,Param
)Param
from a scenario
simulation ScenarioSim
at run-time.
Examples
Get Specified Parameter Value
Create a roadrunner
object to launch the RoadRunner application, and open the project at the specified project location.
rrApp = roadrunner("C:\Project\TestHighwayRoute");
Open the scenario file TrajectoryCutIn.rrscenario
that is
included with the RoadRunner Scenario application.
openScenario(rrApp,"TrajectoryCutIn");
Create a ScenarioSimulation
object ss
.
ss = createSimulation(rrApp);
Get the current simulation status.
simstatus = get(ss,"SimulationStatus");
Get the log data history associated with the simulation.
loggeddata = get(ss,"SimulationLog");
Get the ActorSimulation
objects corresponding to all actors in the scenario.
actors = get(ss,"ActorSimulation");
Get an ActorSimulation
object from the scenario by using the handle
to the Simulink® model that specifies the behavior of this actor.
actorsim = get(ss,"ActorSimulation","SimulinkModel",mdHdl);
Get an ActorSimulation
object by using the System object™ that represents its run-time behavior. This operation is possible only if
an actor is already associated with a MATLAB®
System object.
actorsysobj = get(ss,"ActorSimulation","SystemObject",obj);
Get a specific actor using its corresponding ActorModel
object
name.
actormod = get(ss,"ActorSimulation","ActorModel",actorModel);
Retrieve all the sensors from the simulation.
sensors = get(ss,"SensorSimulation");
