Hi all! I have the next code:
function [y]= mdft (x)
x=x(:);
N=length(x);
v=ones(1,N)
%recurrency factor = z
for a = 0:N-1
z(a+1) = exp(-i*2*pi*a/N);
end
for k=0:N-1
y(k+1) = v*x;
v = v.*z;
end
end
Which calculate the DFT . Now, using this function (mdft) need to implement a code that can make the Inverse DFT.
Thanks for help!
