return a pointer to the coordinates data for the given fit point

Definition at line 235 of file FitData.h.

◆ GetBinData()

void ROOT::Fit::SparseData::GetBinData ( BinData & bd ) const

Transforms the data into a ROOT::Fit::BinData structure.

Definition at line 308 of file SparseData.cxx.

◆ GetBinDataIntegral()

void ROOT::Fit::SparseData::GetBinDataIntegral ( BinData & bd ) const

Same as before, but returning a BinData with integral format (containing bin edges).

◆ GetCoordComponent()

const double * ROOT::Fit::FitData::GetCoordComponent	(	unsigned int	ipoint,
		unsigned int	icoord ) const

inlineinherited

returns a single coordinate component of a point.

This function is threadsafe in contrast to Coords(...) and can easily get vectorized by the compiler in loops running over the ipoint-index.

		double &	error )

Definition at line 278 of file SparseData.cxx.

◆ InitCoordsVector()

void ROOT::Fit::FitData::InitCoordsVector ( )

If std::experimental::simd is not available, there is no vectorization available and the SIMD vector size will always be one.

Then, as every number is a multiple of SIMD vector size, the padding will always be zero.
