MATLAB量化器输出端口问题。

function dout=fcn(din)
%#codegen
Vref=0.5;
N=4;
Level=2^N-1;
Ladder=1:1evel;
m=(din>=Ladder);
ran=normrnd(1,0.05,1,15);
m1=m.*ran;
data=sum(m1);
S=2*Vref/Level;
dout=(data-Level/2)*S;
错误如下不知什么原因，求指教
Error using LowpassSim_SecondOrder (line 48)
    Error in port widths or dimensions. Output port 1 of 'lowpass_DacMismatch/Lowpass  CT Sigma
    Delta/DAC2/MATLAB Function/din' is a one dimensional vector with 1 elements.
