TFFTComplexReal 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 the inverse of the real-to-complex transforms (class TFFTRealComplex) taking complex input (storing the non-redundant half of a logically Hermitian array) to real output (see FFTW manual for more details)

How to use it:

  1. Create an instance of TFFTComplexReal - 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
  3. Set the data (via SetPoints(), SetPoint() or SetPointComplex() functions)
  4. Run the Transform() function
  5. Get the output (via GetPoints(), GetPoint() or GetPointReal() functions)
  6. Repeat steps 3)-5) as needed

For a transform of the same size, but 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 the transform size
  3. In Complex to Real transform the input array is destroyed. It cannot then be retrieved when using the Get's methods.

Arguments sign and kind are dummy and not need to be specified 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.
