Calculate dynamic time warping of two series of values.

This app calculates the warping distance of 2 series.

Installation

Download the file Dynamic Time Warping.opx, and then drag-and-drop onto the Origin workspace. An icon will appear in the Apps Gallery window.

Operation

1. Activate a worksheet or a matrix sheet and click on the app icon
2. Select the two series for input data.
   If the input data are two matrices, they must have the same number of columns.
3. Set Window Size = 0 to get an exact path. To apply a window, set Window Size to a positive integer.
4. Click on the OK button.

Example

To align 2 sequences, you can use the correspondences as index to create the new ones as following.

Note: If you want to output cost matrix, you must call the X-Function by LabTalk and set maxsamp (window size) to 0 and cost to 1. e.g.

dtw -r 2 s1:=1 s2:=2 maxsamp:=0 cost:=1;
