    a4 (:,i)= datStruct.data(1181,:);
    a5 (:,i)= datStruct.data(1197,:);
    a6 (:,i)= datStruct.data(1213,:);
    
    a7 (:,i)= datStruct.data(1250,:);
    
    a8 (:,i)= datStruct.data(1309,:);
    
    a9 (:,i)= datStruct.data(1369,:);
    
    a10 (:,i)= datStruct.data(1425,:);
    a11 (:,i)= datStruct.data(1448,:);
    a12 (:,i)= datStruct.data(1469,:);
    
    a13 (:,i)= datStruct.data(1478,:);
    
    a14 (:,i)= datStruct.data(1476,:);
    a15 (:,i)= datStruct.data(1474,:);
    
    a16 (:,i)= datStruct.data(1445,:);
    
    a17 (:,i)= datStruct.data(1410,:);
    a18 (:,i)= datStruct.data(1372,:);
    a19 (:,i)= datStruct.data(1311,:);
    
    a20 (:,i)= datStruct.data(1233,:);
end;

Please can you help me correct this code. It gives "Struct contents reference from a non-struct array object."

Thanks.

David Clement's answer moved here as a comment.

The line below is producing the error

datStruct = importdata(fileNameArray(i).name);

在 MATLAB Online 中打开

What is the value of

fileNameArray 
% and
fileNameArray(i).name

Is this happening on the first loop (i=1)?
