Matlab Level 2 S-functions and Arrays

My Question is the following:
I want to write an S-Function which takes an n-dimensional input, and gives as output the same Array with an added collumn in a chosen dimension.
When I try that I always end up with errors about a missmatch of dimensions:
"Error in 'SetOutputPortDimensions' method of 'Test_simple/Level-2 MATLAB S-Function1'. The dimension of output port 0 should have been set to [4x1], but was instead set to [4x2]."
&
"Error in port widths or dimensions. Output port 1 of 'Test_simple/Constant' is a [4x1x2] matrix."
How can I fix this missmatch of dimensions?
My code: -----------------------------------------------------------------------------------------------------------------------------------------------------------------
function VPSFUNC4S(block)
setup(block);
function setup(block)
block.NumInputPorts = 1;
block.NumOutputPorts = 1;
block.AllowSignalsWithMoreThan2D = 1;
block.SetPreCompInpPortInfoToDynamic;
block.SetPreCompOutPortInfoToDynamic;
block.InputPort(1).DirectFeedthrough = true;
block.OutputPort(1).DimensionsMode = 'Variable';
block.NumContStates = 1;
block.SampleTimes = [0 0];
block.SetAccelRunOnTLC(false);
block.SimStateCompliance = 'DefaultSimState';
block.RegBlockMethod('SetOutputPortDimensions', @SetOutPortDims);
block.RegBlockMethod('Outputs', @Outputs);
function SetOutPortDims(block, idx, di)
di=block.InputPort(1).Dimensions;
di(2)=di(2)+1;
block.OutputPort(idx).Dimensions = di;
function Outputs(block)
Grosse=size(block.InputPort(1).Data);
X=Grosse(2);
block.OutputPort(1).Data=block.InputPort(1).Data;
block.OutputPort(1).Data=[block.OutputPort(1).Data,zeros(1,Grosse(1))];
for k=1:4;
block.OutputPort(1).Data(k,X+1,1)=block.InputPort(1).Data(k,X,:)+10;
end
