Wm is an N0tilda x N0tilda diagonal matrix

---Matlab code---

Wm = zeros(N0tilda,N0tilda);

----------------------------

given by

Wm = diag(W_{n0}^{-m * 0},W_{n0}^{-m * 1}, ..., W_{n0}^{-m * (N0tilda -1})

I don't make given by Wm

I found code of my answers.

Wm = zeros(N0tilda,N0tilda);
N0tilda = 0:N0tilda-1;
WN0 = exp(-i*2*pi/N0);
Wm = diag(WN0.^N0tilda);
