When I use matlab function block in Simulink. I use another matlab function which contains cell type. But simulink reported error message because of cell. How to avoid this? I'm kind of don't want modify the function because all my functions have cell it's a lot of work to modify them all.

cell() constructor is not supported for code generation

Function 'RealCo.m' (#56.102.111), line 5, column 4: "cell(9,1)" Launch diagnostic report. Component: MATLAB Function | Category: Coder error

Below is the function I called in Matlab Function block in Simulink, Simulink encounter error right in the 5th line.

    function Co=RealCo(q)
    l=60;
    %%%Coordinate Calculation
    %Guess value adopt the unique position below
    *Co=cell(9,1);*
    for i=1
        Co{i}=[0;0;0];
    end
    Co{1}=[sqrt(3)*l/4;0;0];
    Co{2}(1)=-sqrt(3)*l/4;
    Co{2}(2)=l/2;
    Co{2}(3)=0;
    Co{3}(1)=Co{2}(1);
    Co{3}(2)=-l/2;
    Co{3}(3)=0;
    Co{4}=[sqrt(3)*l/4;-l/2;sqrt(3)*l/2];
    Co{5}=Co{4};
    Co{5}(2)=-Co{5}(2);
    Co{6}=Co{4};
    Co{6}(1)=-Co{6}(1);
    Co{6}(2)=0;
    for i=7:9
        Co{i}=Co{i-6};
        Co{i}(3)=sqrt(3)*l;
    end
    guess=zeros(27,1);
    for i=1:3:27
        %When i=1,j=1 i=4,j=2 i=7,j=3 ...
        j=(i-rem(i,3))/3+1;
        guess(i)=Co{j}(1);
        guess(i+1)=Co{j}(2);
        guess(i+2)=Co{j}(3);
    end
    %Use fsolve to solve the system based on current value of q
    fC=@(R)Coor(R,q);
    [result, fval, exit, output]=fsolve(fC,guess);
    % result
    % fval
    % eqns(guess)
    % output
    for i=1:3:27
        %When i=1,j=1 i=4,j=2 i=7,j=3 ...
        j=(i-rem(i,3))/3+1;
        Co{j}=[result(i);result(i+1);result(i+2)];
    end
