How to exit a function execution in MATLAB Function block in simulink?

I have simulating the miller-L code in simulink using MATLAB function block. If the program is run for the first time, I want the output to be like this:

if isempty(flag)
    flag=1;
    con = initial*-1;
    h1 = BinaryInput;
    if BinaryInput == 1
        MillerSignal = [con*ones(1,1) -con*ones(1,1)];
        con=con*-1;
    else
        MillerSignal = [-con*ones(1,2)];
        con = con*-1;
    end
    return;
end

I am not sure whether the return statement is returning out of the function or just from the function block. Is this correct? If not, what is the correct way to do it?

The return would exit the function for that one call. If the internal code for MATLAB Function Block has anything more to execute then it would do so.

Thank you for confirming this. :)
