Function: dft

DFT   Normalized Discrete Fourier Transform
  Usage: f=dft(f);
         f=dft(f,N,dim);

  DFT computes a normalized or unitary discrete Fourier transform. The 
  unitary discrete Fourier transform is computed by
  
                         L-1
    c(k+1) = 1/sqrt(L) * sum f(l+1)*exp(-2*pi*i*k*l/L)
                         l=0

  for k=0,...,L-1.

  The output of DFT is a scaled version of the output from fft. The
  function takes exactly the same arguments as fft. See the help on fft
  for a thorough description.
