 Hi
I have to make a code which can go through vector rr which have length 61914 ...
I have to separate atrial fibrillation from the rr vector ..
I use a method which called Root Mean Square of the Successive Differences (RMSSD) to detect the atrial filibration in rr vector ...

L=61914;

RMSSD=0;

%[M,N]=size(rr);

for k=1:1:L-1

    L=2;
    RMSSD(k)=sqrt((1/(L-1))*((rr(k+1)-rr(k))^2));

end

for

 if (RMSSD(k)) > 0.03
    disp('1');
    else
    disp('0');
    k=k+1
 end

I am new in matlab so my code is not working as it should ... what should i do to get the atrial fibrillation points, if there is an atrial fibrillation so i should get 1 otherwise 0 and store it in a vector called detectRR ... any suggestions please
