output

Query current output of a System object

Syntax

[y1, y2 ..., yn] = output(obj)

Description

[y1, y2 ..., yn] = output(obj) queries the current output of a System object™.

Examples

Query System object for current outputs

Call output to check the current output of a System object.

Consider a System object object defined as,

classdef UnitDelayNondirect < matlab.System
% UnitDelayNondirect Delay input by one time step

properties(DiscreteState)
        State
    end

    methods(Access = protected)
        function resetImpl(obj)
            obj.State = 0; % Initialize states
        end
        function y = outputImpl(obj, ~)
            y = obj.State; % Output current state
 
        end
        function updateImpl(obj,u)
            obj.State = u; % Update state with input
        end
    end
end

Create an instance of the System object and provide it with an input.

a = UnitDelayNondirect();
out = a(1);

Call output to check the output of the System object.

outCurrent = output(a);

Input Arguments

obj — System object

System object

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

Output Arguments

y1, y2 ..., yn — Outputs of System object

outputs

Current outputs calculated from the specified algorithm. The number of outputs must match the number of outputs returned by the getNumOutputs method.
