line up data sets

Hello,

 

Does anyone know a good way to line up two very similar data sets?  for example, a sine and cosine, but they are rough data sets, not clean where I could take a min or max and line them up this way, I need something more clever.  Can anyone point me towards a good algorithm or way to do this?

 

thanks!

Your question is vague. For example, what are your criteria to get them "lined up" and how precisely you need it done? Are the signals periodic, or is there only one point in an entire set at which the measurement is to be "lined up"? Is the noise level such that there might be multiple data ranges where one signal might seem to "line up" with the other?  Please describe and provide typical data sets you see, how you would like them "lined up," and what you have tried so far which didn't work.
