The function extracts features from functional data based on the fast fourier transform. For more details refer to stats::fft.

extractFDAFourier(trafo.coeff = "phase")

## Arguments

trafo.coeff (character) Specifies which transformation of the complex frequency domain representation should be calculated as a feature representation. Must be one of “amplitude” or “phase”. Default is “phase”.

## Value

(data.frame).
