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).
