MATLAB: Issue to begin TestBench generation.

What version of MATLAB are you using? I was not able to reproduce the issue. Please see the attached message.

MATLAB: FFT implementation by theselft

It would be more efficient to use a vector form of the DFT for the coding in matlab. As an example, see below. Note that this method is only best for shorter sequences ,x(n), if you have a larger value for N, then another method would be preferred.

clear variables
close all
%%Implementing the DFT in matrix notation
xn = [0 2 4 6 8];        % sequence of x(n)
N = length(xn);        % The fundamental period of the DFT
n = 0:1:N-1;           % row vector for n
k = 0:1:N-1;           % row vecor for k
WN = exp(-1i*2*pi/N);  % Wn factor 
nk = n'*k;             % creates a N by N matrix of nk values
WNnk = WN .^ nk;       % DFT matrix
Xk = xn * WNnk;        % row vector for DFT coefficients
disp('The DFT of x(n) is Xk = ');
disp(Xk)
magXk = abs(Xk);       % The magnitude of the DFT
%%Implementing the inverse DFT (IDFT) in matrix notation
n = 0:1:N-1;           
k = 0:1:N-1;           
WN = exp(-1i*2*pi/N);  
nk = n'*k;             
WNnk = WN .^ (-nk);    % IDFS matrix
x_hat = (Xk * WNnk)/N; % row vector for IDFS values
disp('and the IDFT of x(n) is x_hat(n) = ');
disp(real(x_hat))
% The input sequence, x(n)
subplot(3,1,1); 
stem(k,xn,'linewidth',2); 
xlabel('n'); 
ylabel('x(n)')
title('plot of the sequence x(n)')
grid
% The DFT
subplot(3,1,2); 
stem(k,magXk,'linewidth',2,'color','r'); 
xlabel('k'); 
ylabel('Xk(k)')
title('DFT, Xk')
grid
% The IDFT
subplot(3,1,3); 
stem(k,real(x_hat),'linewidth',2,'color','m'); 
xlabel('n'); 
ylabel('x(n)')
title('Plot of the inverse DFT, x_{hat}(n) = x(n)')
