Class Fourier1D

java.lang.Object
  net.innig.math.Fourier1D

public class Fourier1D
extends java.lang.Object

Simple one-dimensional FFT, with some very basic optimizations. Not particularly high-tech.

Method Summary

static Fourier1D	create(int size) Factory method allows future etpansion to optimized subclasses (e.g.
void	inverseTransform(double[] fromReal, double[] fromImag, double[] toReal, double[] toImag)
void	transform(double[] fromReal, double[] fromImag, double[] toReal, double[] toImag)

Method Detail

create

public static Fourier1D create(int size)

Factory method allows future etpansion to optimized subclasses (e.g. for non-powers of two).

transform

public void transform(double[] fromReal,
                      double[] fromImag,
                      double[] toReal,
                      double[] toImag)

inverseTransform

public void inverseTransform(double[] fromReal,
                             double[] fromImag,
                             double[] toReal,
                             double[] toImag)
