Apply an Inverse Fourier Transform on a magnitude/phase pair of cubes
Overview
Parameters
Example 1
Description
This program accepts two cubes, most likely acquired from the fft program,
containing the magnitude and phase angle data of a Fourier transformed
image and returns the inverse.

Fixed documentation: example GUI screenshots were missing,
they should now exist. The name of the GUI screenshot was incorrect,
"fft" was changed to "ifft."
