Chris, One way I think of MapThread is as follows: If I wanted to use Table but instead of having values evenly spaced I wanted some odd assortment of values given by a list, then I really want MapThread. If I want to combine two lists of equal length, pairwise, to get something else then I want Inner. These are probably the most common applications of the two commands.

I just know that when I see expressions of a particular structure and I need to transform them, they might be amendable to certain commands... I then try a few of them until I get what I want. That is probably not the best way to go about it, but, eh... o well. -- Chris Chiasson http://chrischiasson.com/contact/chris_chiasson
