class RooFFTConvPdf: public RooAbsCachedPdf



 This class implement a generic one-dimensional numeric convolution of two p.d.f.
 and can convolve any two RooAbsPdfs. The class exploits the convolution theorem

       f(x) (*) g(x) --F--> f(k_i) * g(k_i)

 and calculate the convolution by calculate a Real->Complex FFT of both input p.d.fs
 multiplying the complex coefficients and performing the reverse Complex->Real FFT
 to get the result in the input space. This class using the ROOT FFT Interface to
 the (free) FFTW3 package (www.fftw.org) and requires that your ROOT installation is
 compiled with the --enable-fftw3 option (instructions for Linux follow)

 Note that the performance in terms of speed and stability of RooFFTConvPdf is
 vastly superior to that of RooNumConvPdf

 An important feature of FFT convolutions is that the observable is treated in a
 cyclical way. This is correct & desirable behavior for cyclical observables such as angles,
 but it may not be for other observables. The effect that is observed is that if
 p.d.f is zero at xMin and non-zero at xMax some spillover occurs and
 a rising tail may appear at xMin. This effect can be reduced or eliminated by
 introducing a buffer zone in the FFT calculation. If this feature is activated
 input the sampling array for the FFT calculation is extended in both directions
 and filled with repetitions of the lowest bin value and highest bin value
 respectively. The buffer bins are stripped again when the FFT output values
 are transferred to the p.d.f cache. The default buffer size is 10% of the
 observable domain size and can be changed with setBufferFraction() member function.

 This class is a caching p.d.f inheriting from RooAbsCachedPdf. If this p.d.f
 is evaluated for a particular value of x, the FFT calculate the values for the
 p.d.f at all points in observables space for the given choice of parameters,
 which are stored in the cache. Subsequent evaluations of RooFFTConvPdf with
 identical parameters will retrieve results from the cache. If one or more
 of the parameters change, the cache will be updated.

 The sampling density of the cache is controlled by the binning of the
 the convolution observable, which can be changed from RooRealVar::setBins(N)
 For good results N should be large (>1000). Additional interpolation of
 cache values may improve the result if courser binning are chosen. These can be
 set in the constructor or through the setInterpolationOrder() member function.
 For N>1000 interpolation will not substantially improve the performance.

 Additionial information on caching activities can be displayed by monitoring
 the message stream with topic "Caching" at the INFO level, i.e.
 do RooMsgService::instance().addStream(RooMsgService::INFO,Topic("Caching"))
 to see these message on stdout

 Multi-dimensional convolutions are not supported yet, but will be in the future
 as FFTW can calculate them



 Installing a copy of FFTW on Linux and compiling ROOT to use it

 1) Go to www.fftw.org and download the latest stable version (a .tar.gz file)

 If you have root access to your machine and want to make a system installation of FFTW

   2) Untar fftw-XXX.tar.gz in /tmp, cd into the untarred directory
       and type './configure' followed by 'make install'.
       This will install fftw in /usr/local/bin,lib etc...

   3) Start from a source installation of ROOT. If you now have a binary distribution,
      first download a source tar ball from root.cern.ch for your ROOT version and untar it.
      Run 'configure', following the instruction from 'configure --help' but be sure run 'configure'
      with additional flags '--enable-fftw3' and '--enable-roofit', then run 'make'


 If you do not have root access and want to make a private installation of FFTW

   2) Make a private install area for FFTW, e.g. /home/myself/fftw

   3) Untar fftw-XXX.tar.gz in /tmp, cd into the untarred directory
       and type './configure --prefix=/home/myself/fftw' followed by 'make install'.
       Substitute /home/myself/fftw with a directory of your choice. This
       procedure will install FFTW in the location designated by you

   4) Start from a source installation of ROOT. If you now have a binary distribution,
      first download a source tar ball from root.cern.ch for your ROOT version and untar it.
      Run 'configure', following the instruction from 'configure --help' but be sure run 'configure'
      with additional flags
       '--enable-fftw3',
       '--with-fftw3-incdir=/home/myself/fftw/include',
       '--width-fftw3-libdir=/home/myself/fftw/lib' and
       '--enable-roofit'
      Then run 'make'

Function documentation

RooFFTConvPdf(const char* name, const char* title, RooRealVar& convVar, RooAbsPdf& pdf1, RooAbsPdf& pdf2, Int_t ipOrder = 2)
 Constructor for convolution of pdf1 (x) pdf2 in observable convVar. The binning used for the FFT sampling is controlled
 by the binning named "cache" in the convolution observable. The resulting FFT convolved histogram is interpolated at
 order 'ipOrder' A minimum binning of 1000 bins is recommended.
RooFFTConvPdf(const RooFFTConvPdf& other, const char* name = 0)
 Copy constructor
~RooFFTConvPdf()
 Destructor
const char* inputBaseName() const
 Return base name component for cache components in this case 'PDF1_CONV_PDF2'
void fillCacheObject(RooAbsCachedPdf::PdfCacheElem& cache) const
 Fill the contents of the cache the FFT convolution output
void fillCacheSlice(RooFFTConvPdf::FFTCacheElem& cache, const RooArgSet& slicePosition) const
 Fill a slice of cachePdf with the output of the FFT convolution calculation
Double_t* scanPdf(RooRealVar& obs, RooAbsPdf& pdf, const RooDataHist& hist, const RooArgSet& slicePos, Int_t& N, Int_t& N2, Double_t shift) const
 Scan the values of 'pdf' in observable 'obs' using the bin values stored in 'hist' at slice position 'slicePos'
 N is filled with the number of bins defined in hist, N2 is filled with N plus the number of buffer bins
 The return value is an array of doubles of length N2 with the sampled values. The caller takes ownership
 of the array
RooArgSet* actualObservables(const RooArgSet& nset) const
 Return the observables to be cached given the normalization set nset
 For this p.d.f that is always nset, unless nset does not contain the
 convolution observable, in which case it is nset plus the convolution
 observable
RooArgSet* actualParameters(const RooArgSet& nset) const
 Return the parameters on which the cache depends given normalization
 set nset. For this p.d.f these are the parameters of the input p.d.f.
 but never the convolution variable, it case it is not part of nset
RooAbsGenContext* genContext(const RooArgSet& vars, const RooDataSet* prototype = 0, const RooArgSet* auxProto = 0, Bool_t verbose = kFALSE) const
 Create appropriate generator context for this convolution. If both input p.d.f.s support
 internal generation, if it is safe to use them and if no observables other than the convolution
 observable are requested for generation, use the specialized convolution generator context
 which implements a smearing strategy in the convolution observable. If not return the
 regular accept/reject generator context
void setBufferFraction(Double_t frac)
 Change the size of the buffer on either side of the observable range to frac times the
 size of the range of the convolution observable
RooFFTConvPdf()
{}
TObject* clone(const char* newname) const
{ return new RooFFTConvPdf(*this,newname); }
void setShift(Double_t val1, Double_t val2)
{ _shift1 = val1 ; _shift2 = val2 ; }
Double_t bufferFraction() const
 Return value of buffer fraction applied in FFT calculation array beyond either
 end of the observable domain to reduce cyclical effects
Double_t evaluate() const
{ RooArgSet dummy(_x.arg()) ; return getVal(&dummy) ; }
PdfCacheElem* createCache(const RooArgSet* nset) const
