Have to agree. Ever used MatLab? They have a fairly intuitive approach: 1:5 => [1 2 3 4] 1:2:5 => [1 3 5] 5:1 => empty matrix 5:-1:1 => [5 4 3 2 1] Basically, step size is assumed to be +1, unless provided (in their syntax, as the second argument when 3 arguments are given). Empty ranges produce an emty result. Cheers, Claudio --- Certain disclaimers and policies apply to all email sent from Memetrics.
