fft

Apply a Fourier Transform on a cube

This programs takes a single input cube, applies a Fourier Transform, and stores the result in two bands of an output cube containing the magnitude and phase angle data. If the original image has dimensions that are not powers of two, it is automatically padded with zeroes. These images can then be used in the ifft program to recover the original.
