[SOLVED] Please find my simple error in syndrome function in matlab

[joserse46]

It will only return the syndrome and not k(error in kth position)
I wrote a test function to return two values and it work, but for some reason it's not returning the 2 values I want.
thanks in advance. example msg r1 = [1 0 1 1 1 0 1 0 1 0 0 0 1 0 1] should return s = [0 1 0 1] (which it does) and k = 11

function[s,k] =  getsyndm(msg)
h_t = [1 0 0 0 ;
    0 1 0 0 ;
    0 0 1 0 ;
    0 0 0 1 ;
    1 0 0 1 ;
    1 1 0 1 ;
    1 1 1 1 ;
    1 1 1 0 ;
    0 1 1 1 ;
    1 0 1 0 ;
    0 1 0 1 ;
    1 0 1 1 ;
    1 1 0 0 ;
    0 1 1 0 ;
    0 0 1 1 ];

s = mod(msg*h_t,2);

if s(1) == 0 && s(2) == 0 && s(3) == 0 && s(4) == 0
    k = 0;
elseif s(1) == 0 && s(2) == 0 && s(3) == 1 && s(4) == 1
    k = 15;
elseif s(1) == 0 && s(2) == 1 && s(3) == 1 && s(4) == 0
    k=14;
elseif s(1) == 1 && s(2) == 1 && s(3) == 0 && s(4) == 0
    k=13;
elseif s(1) == 1 && s(2) == 0 && s(1) == 1 && s(4) == 1
    k=12;
elseif s(1) == 0 && s(2) == 1 && s(3) == 0 && s(4) == 1
    k=11;
elseif s(1) == 1 && s(2) == 0 && s(3) == 1 && s(4) == 0
    k=10;
elseif s(1) == 0 && s(2) == 1 && s(3) == 1 && s(4) == 1
    k=9;
elseif s(1) == 1 && s(2) == 1 && s(3) == 1 && s(4) == 0
    k=8;
elseif s(1) == 1 && s(2) == 1 && s(3) == 1 && s(4) == 1
    k=7;
elseif s(1) == 1 && s(2) == 1 && s(3) == 0 && s(4) == 1
    k=6;
elseif s(1) == 1 && s(2) == 0 && s(3) == 0 && s(4) == 1
    k=5;
elseif s(1) == 0 && s(2) == 0 && s(3) == 0 && s(4) == 1
    k=4;
elseif s(1) == 0 && s(2) == 0 && s(3) == 1 && s(4) == 0
    k=3;
elseif s(1) == 0 && s(2) == 1 && s(3) == 0 && s(4) == 0
    k=2;
else
    k=1;
end

end

well an hour later I solved my own problem I was calling the function getsyndm(r1) instead of [s,k] = getsyndm(r1), I know it was easy.
