Details The function performs Dynamic Time Warp (DTW) and computes the optimal alignment between two time series x and y, given as numeric vectors. The “optimal” alignment minimizes the sum of distances between aligned elements. Lengths of x and y may differ. WebDynamic time warping makes a particular assumption on your data set: one vector is a non-linear time-streteched series of the other. But it also assumes that the actual values are on the same scale. Lets say you have: x = 1..10000, a ( x) = 1 ⋅ sin ( 0.01 ∗ x), b ( x) = 1 ⋅ sin ( 0.01234 ∗ x), c ( x) = 1000 ⋅ sin ( 0.01 ∗ x). greencross vets preston
