MATLAB: Subscripted assignment dimension mismatch error

Question

Subscripted assignment dimension mismatch (size [1 x :?] ~= size [:? x :?]).

Hi, I m working on the code below and I need to convert it to C. When I use the MATLAB coder. It gives me this error.

M = [1 2 3 4;4 5 6 7;7 8 9 9;10 11 12 3;13 14 15 6];
    rows = size(M,1);
    col = size(M,2);
    deg = 3;
    var_deg = repmat(deg,[1,size(M,2)]);
    max_deg = max(var_deg);
    A = zeros(max_deg^col,col);
    for i=1:col
        A(:,i) = mod(floor((1:max_deg^col)/max_deg^(i-1)),max_deg);
    end
    A = fliplr(A);
    A = A(sum(A,2)<=max_deg,:);
    B = diag(repmat(max_deg,[1,col]));
     A = [A;B];
    N_in = size(A,1);
    %X = zeros(rows,N_in);
    for i=1:rows
        P=repmat(M(i,:),[N_in,1]);
        C=P.^A; 
        ran2=1;
        for j=1:col
       ran2=ran2.*C(:,j);
        end
       *X(i,:) = ran2;*
     end

Here X(i,:) = ran2; in this line , it gives me the above error and I m not sure what to do. Please help!

Replace

ran2=1;

with

ran2 = ones(size(C,1),1);

so that you are not changing the size of ran2
