close all
x=input('Enter the sequence:');
n=input('Enter the time sample:');
N=input('Enter value greater than or equal to length(x)');
if(N>length(x))
for i=1:N-length(x)
x=[x 0];
end
end
X=[];
xx=0;
for k=0:N-1
for n=0:N-1
xx=xx+x(n+1)* exp(-j*2*pi*n*k/N);
end
X=[X xx];
xx=0;

Great video! It would be good to have a video for IDFT for comparison

[vermatushant]

please share the matlab code for idft without using any inbuilt function as well

Hi, I want to do DFT coding for audio

[syedfariduddin]

why this doesn't work?
k = 0 : N-1
for i =1:N
X(i) =
end

I need FFT code without using intrinsic function

[dharantejav]

please explain me.. why this part of code is not working for sigma code?
for k=1:N
XK(k) =
end
