Details:

When I use a range or with a vector, I haven't the same result.

n = 20480;
step = 2 * pi * 1/250e6 * 10e6;

tmp1 = step * (1:n);
tmp2 = step * [1:n];

max(abs(tmp1 - tmp2)) # Must be equal to 0


I have tested this script with octave 3.8, 4.0 and 4.2, this bug occurs but
with matlab 7.11 I obtain the right result.
