hi, i am trying to add a function blockin my simulink that determines the skewness for specific width bit i am getting Nan as a output. if i run the same fuction separately using script and command window i am getting the output. the only problem is with simulink. please help me out of this. my input is [20385 1] and output will [1 200].

function result_k1= fcn(u)
%#codegen
result_k1=zeros(1, 200);
window_width=50;
for j=1:170
        window_m1=u((j:window_width+(j-1)));  
        window_m11=window_m1(:);
        %result_k1(j)=kurtosis(window_m11);
        result_k1(j)=skewness(window_m11);
       
        
end
