FFT

scalation.calculus.FFT

object FFT

The FFT object provides a method to transform a signal in the time domain (e.g., a times series) in its representation in the frequency domain. The inverse transform is also provided.

Concrete methods

Transform a signal in the time domain into its representation in the frequency domain using the Cooley–Tukey Fast Fourier Transform algorithm. The values are updated in place. FIX - algorithm should allow signals of any size

Value parameters

x: the signal in the time domain as a vector of Complex numbers
