Class DiscreteFourierTransform

  • public class DiscreteFourierTransformextends BasicTransform
    The Discrete Fourier Transform (DFT) is - as the name says - the discrete version of the Fourier Transform applied to a discrete complex valued series. While the DFT can be applied to any complex valued series; of any length, in practice for large series it can take considerable time to compute, while the time taken being proportional to the square of the number on points in the series.
