One of the interface classes to the FFTW package, can be used directly or via the TVirtualFFT class.

Only the basic interface of FFTW is implemented. Computes complex input/output discrete Fourier transforms (DFT) in one or more dimensions. For the detailed information on the computed transforms please refer to the FFTW manual, chapter "What FFTW really computes".

How to use it:

Create an instance of TFFTComplex - this will allocate input and output arrays (unless an in-place transform is specified)
Run the Init() function with the desired flags and settings
Set the data (via SetPoints(), SetPoint() or SetPointComplex() functions)
Run the Transform() function
Get the output (via GetPoints(), GetPoint() or GetPointComplex() functions)
Repeat steps 3)-5) as needed

For a transform of the same size, but with different flags or sign, rerun the Init() function and continue with steps 3)-5)

NOTE:

running Init() function will overwrite the input array! Don't set any data before running the Init() function
FFTW computes unnormalized transform, so doing a transform followed by its inverse will lead to the original array scaled by the transform size
