Lomont1FFT Class Reference

Lomont1FFT, an implementation of the FFT algorithm using a lightweight complex number class. Real valued data is read into the FFT function in an array of alternating real and complex values, converted to complex numbers, passed through the FFT, and converted back. This is quite inefficient.

Member Function Documentation

FFT()

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

inlinevirtual

Compute the forward or inverse FFT of data, which is complex valued items, stored in alternating real and imaginary real numbers. The length must be a power of 2.

Parameters

data	input/output
forward	forward/reverse

Implements LomontFFTBase.

RealFFT()

override 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	array of values and output
forward	forward/reverse flag

Reimplemented from LomontFFTBase.
