Detailed Description

Matlab wrapper for dynamic time warping.

The script can be used to calculate the warping-path for either a given distance matrix between individual points in two signals, or by giving the (potential multidimensional) signals directly.

It returns the warping path (that is corresponding elements in both series as a 2 x M integer-array).

The MATLAB-interface is as follows:

[ path ] = dtwpath( s1, s2 ); s1 and s2 are matrices or vectors giving the signals to be warped.

[ path ] = dtwpath( s1, s2, metric ); s1 and s2 are matrices or vectors giving the signals to be warped. metric is a string giving the distance metric.

Todo:

implement this!

[ path ] = dtwpath( distmat ); distmat is the n x n pointwise distance matrix between signal points.
