getDiscreteState

Get the discrete states of a System object

Syntax

discreteStates= getDiscreteState(obj)

Description

discreteStates= getDiscreteState(obj)returns a struct discreteStates of internal state value properties, which have the DiscreteState attribute. The field names of the struct are the object’s DiscreteState property names. You can restrict or change the values returned by getDiscreteState method by overwriting the getDiscreteStateImpl method.

Examples

Get Discrete State Values

Use the getDiscreteStateImpl method in your class definition file to customize the behavior of getDiscreteState method. The System object contains discrete states value and power. A nontunable parameter keepTrackdetermines the states displayed by this method.

Declare the behavior of getDiscreteState using getDiscreteStateImpl method in the class definition file.

methods (Access = protected)
   function s = getDiscreteStateImpl(obj)
        if obj.keepTrack
            s.value = obj.value;
            s.power = obj.power; 
        else 
            s.value = obj.value; 
        end 
   end
end

Use getDiscreteState to access the discrete states of the method.

discreteStates = getDiscreteState(obj);

Input Arguments

obj — System object™

System object

System object handle used to access properties, states, and methods specific to the object.

Output Arguments

discreteStates — Discrete state values

struct

Discrete state values returned as a struct.
