Twiddle Factor in MATLAB

Just create a new file with extension .m and paste the code below in that .m file. Then Run it.

clear all;

clc;

N=input('enter the no. of points : ');

W=exp((-j*2*pi)/N);

K=2;

%VERIFICATION OF SYMETRY PROPERTY

LHS_Symetry=W^(N/2+K)

RHS_Symetry=-W^K

fprintf('LHS_Symetry = RHS_Symetry (Proved)')

%VERIFICATION OF PERIODICITY PROPERTY

LHS_Periodicity=W^(K+N)

RHS_Periodicity=W^K

fprintf('LHS_Periodicity = RHS_Periodicity (Proved)')
