How to replace cell array in tlc file

I use some cell array in s-function, now I need to write a tlc file to "code generate"

Is there any easy way to replace cell array ? Or I need use matrix and for loop to overwrite it?

Here is the code of cell array

Np=10;    
Q_cell=cell(Np,Np);
for i=1:1:Np;
    for j=1:1:Np;
        if i==j
            %Q_cell{i,j}=[1 0;0 11;];
            Q_cell{i,j}=[1 0 0 ;0 1 0;0 0 1];
        else
            Q_cell{i,j}=zeros(Ny,Ny);               
        end
    end
end
Q=cell2mat(Q_cell);
