getDiscreteStateImpl

Class: matlab.System

Discrete state property values

Syntax

s = getDiscreteStateImpl(obj)

Description

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

Run-Time Details

getDiscreteStateImpl is called by the setup method. For details, see

Detailed Call Sequence.

Method Authoring Tips

  • You must set Access = protected for this method.

  • You cannot modify any properties in this method.

Input Arguments

expand all

System object handle used to access properties, states, and methods specific to the object. If your getDiscreteStateImpl method does not use the object, you can replace this input with ~.

Output Arguments

expand all

State values, returned as a struct.

Examples

expand all

Use the getDiscreteStateImpl method in your class definition file to get the discrete states of the object.
