Detailed Description

Represent a base class for a FFT

Member Function Documentation

FFT()

abstract void FFT ( double []  data, bool  forward  )

pure virtual

Implement a Fourier Transform

Parameters

data	contains the data as (real,imaginary) interleaved sequence. Sequence must be a power of 2, say 2^n data points, thus array would be 2*2^n in length
forward	true for a foward transform, else false for a reverse transform

Implemented in Lomont4FFT, Lomont1FFT, Lomont2FFT, and Lomont3FFT.

Initialize()

virtual void Initialize ( int  size )

inlinevirtual

For static initialization for a given size, call this

Parameters

size

Reimplemented in Lomont4FFT.

RealFFT()

virtual void RealFFT ( double []  data, bool  forward  )

inlinevirtual

Perform a FFT on real data, returning half the (symmetric) complex transform as (real,imaginary) interleaved pairs

Parameters

data
forward

Reimplemented in Lomont4FFT, and Lomont1FFT.
