Hi
I am having difficulty understanding the 'maxsamp' argument for the dynamic time warping 'dtw' distance function. The explanation given in the below documentation seems to be quite brief and was not able to find other relevant documents around.

Would appreciate if someone can give an example or explanation.
Best
Baran

Fit a straight line over x and y, like
coeffs = polyfit(x, y, 1)
Now, as you go along doing the warping, ignore any sample that is more than maxsamp away from that line.
This sort of declares anything too far away from the average to be an outlier that should be ignored in calculating the warping.
