A =[1 2;3 4];
B=[2 3;5 6];
C=[A;B] ( should be in 2*2 )

Ran in:
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
