Vectorized implementation

[MatthieuBizien]

StackOverflow just reminded me of my old post, where I made your implementation of dtw 435 times faster. I have no use of it now (the Kaggle competition has ended years ago), but maybe others could use it.

The solution is very simple, just removing the for loops :) It would however needs some adaptation as your code have changed since.

Thanks, indeed this could really save some CPU time :)
I'l try to integrate it when I have some free time!

Could you elaborate a little more on this?
For instance, which part of the codes should I change?
