Can i use cell inside user defined Matlab function in Simulink?

function y = fcn(u)

%#codegen

A=cell(1,4);

p=zeros(3,12);

for i=1:4

A{:,i}=rotx(u(i));

end

p=cell2mat(A);

y=reshape(p,[3,12]);

end

function R = rotx(t)

    ct = cos(t);

    st = sin(t);

    R = [
        1   0    0
        0   ct  -st
        0   st   ct
        ];
end

I am trying to use cell and cell2mat inside a user defined Matlab function in Simulink. The above code (function y = fcn(u)) gives error "The function 'cell2mat' is not supported for standalone code generation". How can i proceed to use cell and extract it as matrix for simulink?

I understand that you want to generate C code from this MATLAB function. However, cell arrays are not supported for code generation. A workaround would be to use structures in place of cell arrays as code generation for structures is supported.
