My answer is singular, but how can I get rid of it

Hi, I want to get a result of 6*6 matrix, but my answer is singular. I don't know how I can solve it. my answer should look like as

    0.0228    0.0092    0.3766         0         0         0
    0.0096    0.0205    0.3765         0         0         0
    0.0084    0.0079    2.1596         0         0         0
         0         0         0    0.0054         0         0
         0         0         0         0    0.0063         0
         0         0         0         0         0    0.0060

please help me. Thanks in advance

program is :

S_i = Eshelby_tensor;
C_m = Tangent_tensor_matrix;
C_i = Tangent_tensor_inclusion;
II = [1, 0, 0, 0, 0, 0;
      0, 1, 0, 0, 0, 0;
      0, 0, 1, 0, 0, 0;
      0, 0, 0, 1, 0, 0;
      0, 0, 0, 0, 1, 0;
      0, 0, 0, 0, 0, 1];

C_SC_two = rand(6,6);       
for j = 2:6
    for i = 2:6
        c_i =0.2;
        C_SC_two(j,i) = C_m + ((c_i)*(C_i - C_m)) *  (II* (1-c_i)*(S_i)*(C_SC_two(j-1,i-1))^(-1) * (C_i - C_m))^(-1);
    end
end

Use.* instead of *
