class TFFTRealComplex: public TVirtualFFT

default

For 1d transforms
Allocates memory for the input array, and, if inPlace = kFALSE, for the output array

For ndim-dimensional transforms
Second argurment contains sizes of the transform in each dimension

Destroys the data arrays and the plan. However, some plan information stays around
until the root session is over, and is reused if other plans of the same size are
created

Creates the fftw-plan

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

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
   performanc
"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.

Computes the transform, specified in Init() function

Fills the array data with the computed transform.
Only (roughly) a half of the transform is copied (exactly the output of FFTW),
the rest being Hermitian symmetric with the first half

Returns the real part of the point #ipoint from the output or the point #ipoint
from the input

Returns the real part of the point #ipoint from the output or the point #ipoint
from the input

Returns the point #ipoint.
For 1d, if ipoint > fN/2+1 (the point is in the Hermitian symmetric part), it is still
returned. For >1d, only the first (roughly)half of points can be returned
For 2d, see function GetPointComplex(Int_t *ipoint,...)

For multidimensional transforms. Returns the point #ipoint.
In case of transforms of more than 2 dimensions,
only points from the first (roughly)half are returned, the rest being Hermitian symmetric

Returns the input array// 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.

Fills the argument arrays with the real and imaginary parts of the computed transform.
Only (roughly) a half of the transform is copied, the rest being Hermitian
symmetric with the first half

Fills the argument arrays with the real and imaginary parts of the computed transform.
Only (roughly) a half of the transform is copied, the rest being Hermitian
symmetric with the first half

Set the point #ipoint

For multidimensional transforms. Set the point #ipoint

Set all input points

Sets the point #ipoint (only the real part of the argument is taken)

Set all points. Only the real array is used

allowed options:
"ES"
"M"
"P"
"EX"
