Variable size output in level-2 matlab S-functions

Question

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!...
