mlpy - Dynamic Time Warping depends on x?

Question

I am trying to get the distance between these two arrays shown below by DTW.

Answer 1

Obviously, the curves are not identical, and therefore the distance function must not be 0 (otherwise, it is not a distance by definition).

What IS "relatively large"? The distance probably is not infinite, is it?

140 points in time, each with a small delta, this still adds up to a non-zero number.

The distance "New York" to "Beijing" is roughly 11018 km. Or 1101800000 mm.

The distance to Alpha Centauri is small, just 4.34 lj. That is the nearest other stellar system to us...

Compare with the distance to a non-similar series; that distance should be much larger.
