Since R2015(b?), a simple way to find out which toolbox you're missing for a particular function is simply to type that function name in the command window and press enter. The error message will tell you the name of the missing toolbox.

Of course, if you've got the toolbox, just looking it up in the documentation, doc dtw, will tell you which toolbox it belongs to.
