clc;clear
C1 = input("Please enter a code to break: " , "s");
if length(C1) ~= 6
    disp("Decoy message: Not a six-digit number.");
else
   A = sum(C1 - '0');
   if 
       mod(A , 2) = 1;
    disp("Decoy message:Sum is odd.");
   else
    C2 = (C1(1) - '0') * (C1(2) - '0') - (C1(3) - '0');
    switch C2
        case 1
            disp("Monday")
        case 2
            disp("Tuesday")
        case 3
            disp("Wednesday")
        case 4 
            disp("Thursday")
        case 5
            disp("Friday")
        case 6 
            disp("Saturday")
        case 7
            disp("Sunday")
        otherwise
            disp("Decoy message:Invalid rescue day.");
    end

My homework does not let me to use if elseif for the part C2, only switch statement is allowed... Can you please show me how to do this with switch statement?

?? You already seem to be using switch(), so I am not clear as to what you want to do?

Perhaps you are looking for

   if mod(A , 2) == 1;
     disp("Decoy message:Sum is odd.");
   elseif some condition
       your switch code
   else
       some more code for when the sum is odd but the switch does not apply
   end
