I would like to do a For loop with a jump 2*Pi instead of 1.
For[j = 0, j <= nmax, (incr = 2 Pi), ...]
Actually what I want to do is
j = n 2 Pi, where
n takes values from 0 to
n-1, so the iteration stops at
nmax = (n - 1) 2 Pi.
I know this is a pretty trivial question, but I have not found anything equivalent in the "Documentation center".
