Do the FFT: specify +1 or -1 to indicate forward or inverse transform, or specify the user-defined name string for the direction. User provides separate input and output fields optional argument constInput indicates whether or not to treat the input Field argument f as const. If not, we can use it as a temporary in order to avoid an additional data transpose.
