Hi,
I"m trying to get a vector complex output from my S-function. It seems that level-1 M file can't output a complex vector. Hence I'm using level-2 M file. However, I'm getting the error message as "Error in 'SetOutputPortDimensions' method of 'XXXX/Level-2 M-file S-Function'. The dimensions of output port 0 should have been set to [1], but was instead set to [2]."

My code is as follows. Please help me out. If there is a way to do get complex vector output in level-1 file, pls. let me know.

function bls_rentian_s2(block)
setup(block);
function setup(block)

block.NumDialogPrms = 4;
% Register number of ports
block.NumInputPorts = 1;
block.NumOutputPorts = 1;
block.OutputPort(1).Complexity = 'c';
block.SampleTimes = [0 0];
block.RegBlockMethod('SetOutputPortDimensions', @SetOutPortDims);
block.RegBlockMethod('Outputs', @Outputs);

function SetOutPortDims(block, idx, di)

block.OutputPort(1).Dimensions = 2;%di;%[1,2];
% block.InputPort(1).Dimensions = di;

function Outputs(block)
n2 = block.DialogPrm(1).Data;
n3 = block.DialogPrm(2).Data;
lambda = block.DialogPrm(3).Data;
h = block.DialogPrm(4).Data;

n1 = 1;
pi = 3.14;
r_12 = (n1-n2)/(n1+n2);
r_23 = (n2-n3)/(n2+n3);
delta = 4*pi*n2*h/lambda;

block.OutputPort(1).Data = [r_12;r_23];
