how to create a 22 matrix by combining two matrices with size of 22 ie A and B are 22 and i want to get C also 22

A =[1 2;3 4];
B=[2 3;5 6];
switch randi(12)
    case 1; C = A + B;
    case 2; C = A - B;
    case 3; C = B - A;
    case 4; C = A .* B;
    case 5; C = A * B;
    case 6; C = B * A;
    case 7; C = A ./ B;
    case 8; C = B ./ A;
    case 9; C = A.^B;
    case 10; C = B.^A;
    case 11; C = mod(A,B);
    case 12; C = mod(B,A);
end
C
C = 2×2
