Calculate FFT frequencies of the amplitudes calculated with the FFT
Calculates the exact Fourier frequencies for spectra calculated via FFT. This functionality is not provided by Matlab, hence requires custom function. Currently only works on vectors/1D arrays.
It is not straightforward due to how the operation is done on a bit-level. The first coefficient is 0 Hz (the DC component) but higher negative and positive frequencies are ordered in a specific way, separated at the Nyquist frequency (also optionally returned by the function).
