Finding distance between values in a column vector

Basically I used the findpeaks function to find the time values of a graph I had. Using this code shown below.

[PeakHeight,PeakTime]=findpeaks(ECG_Clean);
disp(PeakTime)

This gave the time for when each peak occured as a column vector. I want to find the average time between each peaks but when I do the following function it gives me the average time and not the average time gap between each peak.

AvgPeakDistance = sum(PeakTime(:))/numel(PeakTime);

So basically, I was wondering how to find the distance between values in a column vector, so that I could find the average of it.

Thanks

dPeakTime = diff(PeakTime) ; % get the difference between consecutive PEak times 
AvgPeakDistance = sum(dPeakTime)/numel(dPeakTime);

Thanks it works perfectly
