can anybody post the matlab code for assigning the entire qrs wave to zero and only keeping the p and t wave

i found out the startiong point of qrs wave (q point) and ending point(t point);;now i just have to eliminate the entire wave between these points

If this is just a general question about setting points in a vector to zero, once you have the boundary indices, it's easy.

Ex:

 x = 1:10;
 x = [x fliplr(x)];
 idxbeg = find(x>5, 1,'first');
 idxend = find(x>5, 1,'last');
 % idxbeg and idxend are the beginning and ending indices
 x(idxbeg:idxend) = 0;

thankyou for your answer.but it doesnt show the required output...the size of my signal is 6000 samples and using the above program shows no change and the signal remains the same. i also have to implement the above code in an loop as the starting and end point change as the signal goes from one cycle to another
