Inconsistent distance to Matlab

[castdice]

I am trying to use the package in my work but found the dtw distance computed by this package is different from some other version of dtw implementations. Here is the code snippet:

from dtw import *
x=[0, 1, 2, 3, 4, 5, 6, 7, 8]
y=[1, 2, 3, 4, 5, 6, 7, 7, 10]
alignments = dtw(x, y)
dtw_dist = alignments.distance
print("DTW package result: {}".format(dtw_dist))

and the output is

DTW package result: 4.0

However, the output of matlab is:

x=[0, 1, 2, 3, 4, 5, 6, 7, 8]
y=[1, 2, 3, 4, 5, 6, 7, 7, 10]
dtw(x, y)

ans = 3

The default distance for both functions is euclidean. I am new to this field. Did I do something wrong? Thank you for your patience.
