Hi iam using Matlab 2018a

When using DTW function for two single vectors on X and Y the DTW works good

but when using the 2D data as matrix input for DTW , the finction returns the absolute value for both metrics 'euclidean as well as absolute

X1=[3 7;5 9];

Y1=[4 5;2 6];

dist=dtw(X1,Y1,'euclidean')

& dtw(X1,Y1,'absolute')

both returns same answer

I have noticed this issue as well. It seems the function always returns the 1-norm, irrespective of the "metric" argument.
