getOutputSize
Get the size of outputs of a System object
Description
[
returns the size of each output of a System object™. The number of outputs must match the number of outputs returned by the
sz_1, sz_2, ..., sz_n
] = getOutputSize(obj
)getNumOutputs
method.
Examples
Get the output sizes of a System object
Call getOutputSize to get the output sizes of a System object.
Consider a System object object defined as,
classdef UnitDelay < matlab.System % UnitDelayNondirect Delay input by one time step properties(DiscreteState) State Step end methods(Access = protected) function resetImpl(obj) obj.State = 0; % Initialize states obj.Step = 1; end function [y1, y2] = stepImpl(obj,u) y1 = obj.State; % Output current state y2 = obj.Step; obj.State = u; obj.Step = obj.Step + 1; end function [sz1, sz2] = getOutputSizeImpl(obj) sz1 = [1,1]; % Specify size of output port sz2 = [1,1]; end function [flag1, flag2] = isOutputFixedSizeImpl(obj) flag1 = true; % Specify if output is fized size flag2 = true; end function [c1, c2] = getOutputDataTypeImpl(obj) c1 = 'double'; % Specify output datatype c2 = 'double'; end function [c1, c2] = isOutputComplexImpl(obj) c1 = false; % Specify if output is complex c2 = false; end end end
Create an instance of the System object and provide it with an input.
a = UnitDelay(); [out, step] = a(1);
Call getOutputSize to get the output sizes of the System object.
[sz1, sz2] = getOutputSize(a);
Input Arguments

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