class ROOT::Fit::UnBinData: public ROOT::Fit::FitData


   Class describing the unbinned data sets (just x coordinates values) of any dimensions

              There is the option to construct UnBindata copying the data in (using the DataVector class)
              or using pointer to external data (DataWrapper) class.
              In general is found to be more efficient to copy the data.
              In case of really large data sets for limiting memory consumption then the other option can be used
              Specialized constructor exists for using external data up to 3 dimensions.

              When the data are copying in the number of points can be set later (or re-set) using Initialize and
              the data are pushed in (one by one) using the Add method.

Function documentation

explicit UnBinData(unsigned int maxpoints = 0, unsigned int dim = 1 )

      constructor from dimension of point  and max number of points (to pre-allocate vector)

UnBinData(const DataOptions & opt, const DataRange & range, unsigned int maxpoints = 0, unsigned int dim = 1 )

      constructor from options and range

UnBinData(unsigned int n, unsigned int dim, Iterator dataItr )

      constructor for multi-dim external data
      Uses as argument an iterator of a list (or vector) containing the const double * of the data
      An example could be the std::vector<const double *>::begin

UnBinData & operator=(const ROOT::Fit::UnBinData& )

 assignment operator  (private)

{ return *this; }

unsigned int NPoints()

      return number of contained points

{ return fNPoints; }

unsigned int NDim()

      return coordinate data dimension

{ return fDim; }
