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

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: ');
disp(Twiddle_Factors);
