Variable size output in level-2 matlab S-functions

Hello,

I am trying to write a level-2 matlab S-function with a variable sized output. However, unlike official examples and documentation the size of the ouput is not dependent on the input or parameters. I am struggling to create this as the error dialogue box is unhelpful.

I would really appreciate any help that can be provided to solve this issue. A minimum example of the code is

function myFunc(block)
setup(block);

%endfunction

%%Function: setup ===================================================
function setup(block)

% Register number of ports
block.NumInputPorts  = 1;
block.NumOutputPorts = 2;

% Setup port properties to be inherited or dynamic
block.SetPreCompInpPortInfoToDynamic;
block.SetPreCompOutPortInfoToDynamic;

% Override input port properties
block.InputPort(1).Dimensions = 1;
block.InputPort(1).DatatypeID = 0;  % double
block.InputPort(1).Complexity = 'Real';
block.InputPort(1).DirectFeedthrough = false;

% Override output port properties
block.OutputPort(1).DimensionsMode = 'Variable';
block.OutputPort(1).Dimensions = 1; %'Variable';
block.OutputPort(1).DatatypeID = 0; % double
block.OutputPort(1).Complexity = 'Real';
block.OutputPort(1).SamplingMode = 'Sample';

block.OutputPort(2).DimensionsMode = 'Variable';
block.OutputPort(2).Dimensions = 1; %'Variable';
block.OutputPort(2).DatatypeID = 0; % double
block.OutputPort(2).Complexity = 'Real';
block.OutputPort(2).SamplingMode = 'Sample';

% Register parameters
block.NumDialogPrms     = 0;

block.SampleTimes = [-1 0];

% SetInputPortSamplingMode:
block.RegBlockMethod('SetInputPortSamplingMode', @SetInpPortFrameData);

block.SimStateCompliance = 'DefaultSimState';

block.RegBlockMethod('InitializeConditions', @InitializeConditions);
block.RegBlockMethod('Start', @Start);
block.RegBlockMethod('Outputs', @Outputs);     % Required
block.RegBlockMethod('Terminate', @Terminate); % Required

%end setup
function InitializeConditions(block)
%%INITIALIZE INDICES AS DOUBLE %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

%%here I initialize some parameters that are used during the algorithm
% for e.g.
a = 1;
b = 2;
% etc.

%end InitializeConditions

function Outputs(block)

xi  = block.InputPort(1).Data;

% run some logic here with xi, a, b, etc.
% obtain two matrices
% A of size (integer X 2)
% b of size (integer X 1)

% assign outputs
[rowCount_A, colCount_A] = size(A);
block.OutputPort(1).CurrentDimensions = [rowCount_A, colCount_A];
block.OutputPort(1).Data = A;

[rowCount_b, colCount_b] = size(b);
block.OutputPort(2).CurrentDimensions = [rowCount_b, colCount_b];
block.OutputPort(2).Data = b;

%end Outputs

%%Set the sampling of the input ports
function SetInpPortFrameData(block, idx, fd)

    block.InputPort(idx).SamplingMode = fd;
    for ii = 1:block.NumOutputPorts
      block.OutputPort(ii).SamplingMode  = fd;
    end
  % end SetInpPortFrameData

% Set the dimension of the output ports
function setOutputVarDims(block, opIdx, inputIdx, rowCount_A, colCount_A, rowCount_b, colCount_b)
  % Set current (run-time) dimensions of the output
  block.OutputPort(1).CurrentDimensions = [rowCount_A, colCount_A];
  block.OutputPort(2).CurrentDimensions = [rowCount_b, colCount_b];
% end setOutputVarDims

function Terminate(block)
%end Terminate

Thank you!

Regards!...

Is there any answer for this problem I am struggling with the same problem.

Thanks for help
