Calculate Asynchrony/Euclidea​n Distance Between Matches

Find the mutual closest pairwise matches between observations in two vectors

Finds the matches in any two vectors, ideally set up for calculating temporal asynchrony between events (e.g., within a sensorimotor timing experiment).

This function accepts two vectors (e.g., time stamps, drum hits, word onsets) and looks for the mutual closest pairwise matches between successive observations, dropping unpaired points (e.g., extra or omitted events). No point can be paired more than once.

The resultant absolute distances (e.g., asynchrony in milliseconds) between each pair of points are returned as a new vector, plus the indices of paired/unpaired observations.

You can also optionally plot the two input vectors along with their proposed pairings by flagging third optional argument as '1'.
