Bourguignon" writes: > Well, the tuple notion is tained, notably by some > purely functional programming language There are "tuples" in linear algebra books as well, where tuples are pairs, and n-tuples are vectors (or lists) with n elements. Anyway, instead of inventing a new terminology that is supposedly less confusing it is better just to learn the one used. In this case it is very simple at that (1D - vector, 2D or more - array). Otherwise it will be even more confusion as some people are used to the old terminology, to the point where there is diverging sets. This happens all the time with no worries, however in programming it is especially unpractical as all those functions would still be using "vector" and not tuple or whatever, and the people calling them tuples would be lost and think them gone. -- underground experts united http://user.it.uu.se/~embe8573
