If you pass in 2 vectors it returns the unnormalized distance between the vectors, the accumulated distance between them, the length of the warping path (the normalizing factor), and the warping path points.

To compare 2 vectors A and B call:
[Dist,D,k,w]=dtw(A,B)
Dist is the unnormalized distance
D is the accumulated distance
k is the length of the warping path
(the normalizing factor)
w is a matrix containing the points along the warping path
