title: How can I get the full fft coefficients by cufft?
body: <p>I am doing two dimensional fft process by cufft.
  Processing type is real to complex, so the size of out array is NX * (NY / 2 + 1) which is non redundant.
  But I need the full coefficients containing the redundant ones.
  How can i get them all?
  Thanks in advance.</p>
