calculate with Twiddle factor

Does anybody knows how to calculate the Twiddle Factors?

For example: for n=4 you have to do the calculate Wn= e^(-j*2*π)/n and ypu have to do it for a table 4x4. table looks like..

the second is the table after calculate the 4x4

and i need this for calculate twiddle factors for n=8,16,24...

cos(2pi*n*k/N)-j*sin(2pi*n*k/N) , N = 4,8,16, k and n = rows and colums

[Victor Cubedo]

starting n and k in 0

This is one of the possible solutions:

N = 4;
Twiddle_Factors = zeros(N, N);
for k = 0:N-1
    for n = 0:N-1
        Twiddle_Factors(k+1, n+1) = exp(-1i * 2 * pi / N * k * n);
    end
end

disp('Twiddle Factors of size 4-by-4: ');

Twiddle Factors of size 4-by-4: 

disp(Twiddle_Factors);

   1.0000 + 0.0000i   1.0000 + 0.0000i   1.0000 + 0.0000i   1.0000 + 0.0000i
   1.0000 + 0.0000i   0.0000 - 1.0000i  -1.0000 - 0.0000i  -0.0000 + 1.0000i
   1.0000 + 0.0000i  -1.0000 - 0.0000i   1.0000 + 0.0000i  -1.0000 - 0.0000i
   1.0000 + 0.0000i  -0.0000 + 1.0000i  -1.0000 - 0.0000i   0.0000 - 1.0000i
