Hi Daniel,

You need to learn what is a MATLAB function first.

Hi Steven du,

Yes, you are right. I forgot to update it when I extended it for multi-dimensional signals.

Hi Cheung,

If you compute ||a-b||, you will have to use loops. MATLAB loops are slow, and distanceMatrix avoids using loops, thus is very fast.

如果用||a-b||,就需要是用MATLAB循环,而MATLAB循环非常慢。我的distanceMatrix就是一个巧妙避免使用循环的方法,因此很快。

What does MATLAB Compiler do? When I try to run the code, I get an error message for Line 1 (function d=dtw(a,b,w)).

Thanks

I thinks line 19 of dtw.m
ns=length(s);
Ought to be ns=size(s,1)

As length(s)=max(size(s))
