Hi Walter! Small correcting.
cs = cumsum(YourData(:));
moving_average = (cs(10:end) - [0;cs(1:end-10)])/10;

‘But i need overlap between the values as 1:10 then from 2:11 and so on’
Use a moving average filter:
Heart_pulse_avg = filter(ones(1,10), 10, Heart_pulse);

a - your vector;
out = movsum(a,[0 9],'Endpoints','discard')/10;
