TFFTReal Class Reference

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 transforms called r2r in FFTW manual:

  • transforms of real input and output in "halfcomplex" format i.e. real and imaginary parts for a transform of size n stored as (r0, r1, r2, ..., rn/2, i(n+1)/2-1, ..., i2, i1)
  • discrete Hartley transform
  • sine and cosine transforms (DCT-I,II,III,IV and DST-I,II,III,IV) For the detailed information on the computed transforms please refer to the FFTW manual, chapter "What FFTW really computes".

How to use it:

  1. Create an instance of TFFTReal - this will allocate input and output arrays (unless an in-place transform is specified)
  2. Run the Init() function with the desired flags and settings (see function comments for possible kind parameters)
  3. Set the data (via SetPoints()or SetPoint() functions)
  4. Run the Transform() function
  5. Get the output (via GetPoints() or GetPoint() functions)
  6. Repeat steps 3)-5) as needed

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

NOTE:

  1. running Init() function will overwrite the input array! Don't set any data before running the Init() function!
  2. FFTW computes unnormalized transform, so doing a transform followed by its inverse will lead to the original array scaled BY:
    • transform size (N) for R2HC, HC2R, DHT transforms
    • 2*(N-1) for DCT-I (REDFT00)
    • 2*(N+1) for DST-I (RODFT00)
    • 2*N for the remaining transforms

Transform inverses:

  • R2HC<-->HC2R
  • DHT<-->DHT
  • DCT-I<-->DCT-I
  • DCT-II<-->DCT-III
  • DCT-IV<-->DCT-IV
  • DST-I<-->DST-I
  • DST-II<-->DST-III
  • DST-IV<-->DST-IV

NOTE: input and output arrays are overwritten during initialisation, so don't set any points, before running this function!!!!!

1st parameter:

Possible flag_options:

  • "ES" (from "estimate") - no time in preparing the transform, but probably sub-optimal performance
  • "M" (from "measure") - some time spend in finding the optimal way to do the transform
  • "P" (from "patient") - more time spend in finding the optimal way to do the transform
  • "EX" (from "exhaustive") - the most optimal way is found

    This option should be chosen depending on how many transforms of the same size and type are going to be done. Planning is only done once, for the first transform of this size and type.

2nd parameter:

is dummy and doesn't need to be specified

3rd parameter:

transform kind for each dimension 4 different kinds of sine and cosine transforms are available

  • DCT-I - kind=0
  • DCT-II - kind=1
