[edit] Roots of unity

The article says:

The matrix W of size nxn, may be described as a Vandermonde matrix:

W = V(w) where w is a vector w_i = \omega_n^i, the nth root of unity.

This strikes me as badly written... surely the vector w isn't the nth root of unity, but rather the vector consisting of each of the nth roots of unity beginning with 1 and progressing around the origin of the complex plane in an anti-clockwise direction? I'm not quite sure that this is right, so don't want to fix it. JulesH 20:09, 20 November 2006 (UTC)
