    N = input('Enter the the value of N(Value of N in N-Point DFT)');
    x = input('Enter the sequence for which DFT is to be calculated');
    n=[0:1:N-1];
    k=[0:1:N-1];
    WN=exp(-1j*2*pi/N); % twiddle factor
    nk=n'*k;
    WNnk=WN.^nk;
    Xk=x*WNnk;
    MagX=abs(Xk) % Magnitude of calculated DFT
    PhaseX=angle(Xk)*180/pi % Phase of the calculated DFT figure(1);
    subplot(2,1,1);
    plot(k,MagX);
    subplot(2,1,2);
    plot(k,PhaseX);
    -------------*****--------------
    OUTPUT
    Enter the the value of N(Value of N in N-Point DFT)4 Enter the sequence for which DFT is to be calculated [1 2 3 4]
    MagX = 10.0000 2.8284 2.0000 2.8284

    Does the matrix twiddle apply just when we have 4 point of DTF
    for exemple if we have x[n]={1 2 3 4} we can apply twiddle matrix .
    BUT
    if we have for exemple x[n]={1 2 3 } can we apply the twiddle matrix ??

    why sir your all discrete signal processing videos get private ..plz open the videos because we are learning from their and we have reachedthe half of the course then i see you private your videos of discrete signal processing please sir try to understand our feelings and please open the videos for some time thatsa why we are complete our courses soon

    Must response becoz we are following your method.

      U should mention N=? & only then we can solve the problem.. here we see L=4... If N>L then we have to use zero padding method. If N=L then just do (2.pi)/N i.e. the domain will divide in N parts. & phase difference will be (2.pi)/N . and if u find N
