.fourier_frequencies

Computes normalized Fourier frequencies for scalar or vector inputs, which
are evenly spaced between -0.5 and 0.5.

internal

The 'fftab' package stores Fourier coefficients in a tibble and
allows their manipulation in various ways. Functions are available for converting
between complex, rectangular ('re', 'im'), and polar ('mod', 'arg') representations,
as well as for extracting components as vectors or matrices. Inputs can include
vectors, time series, and arrays of arbitrary dimensions, which are restored
to their original form when inverting the transform. Since 'fftab' stores Fourier
frequencies as columns in the tibble, many standard operations on spectral data
can be easily performed using tidy packages like 'dplyr'.
