Plot the time difference between two arrays
显示 更早的评论
Hello, I have a problem and don't now if there is a matlab function to do that. I have several heart rate signal from different technology and I would like to compare the delay between a detection between these technology.
For the detection I use the function findpeak, so I have an array of position for each signal. Sadly sometimes the function doesn't detect a peak or detect 2 instead of one, so the arrays are not exactly the same length. I can plot the value but cannot make a point by point comparaison.. There is a function in order to compare the array point by point to see the varaition of delay between the technology? for exemple to compare the nearest point? Thank you, Pierre

If you upload an example of (a) a troublesome signal where the peaks are difficult to detect (b) another signal to calculate the lag, then it'd be easier to help! Don't forget to indicate the correct peaks of the former.
