createShapedOutput()

MDHistoWorkspace_sptr createShapedOutput	(	IMDHistoWorkspace const *const	inWS,
		std::vector< std::vector< double > >	pbins,
		Logger &	logger
	)

Create the output workspace in the right shape.

Parameters

inWS	: Input workspace for dimensionality
pbins	: User provided binning
logger	: Logging object

performWeightedSum()

void performWeightedSum	(	MDHistoWorkspaceIterator const *const	iterator,
		const MDBoxImplicitFunction &	box,
		double &	sumSignal,
		double &	sumSQErrors,
		double &	sumNEvents
	)

Perform a weighted sum at the iterator position.

This function does not increment the iterator. Masked bins do not contribute.

Parameters

iterator	: Iterator to use in sum
box	: Box implicit function defining valid region.
sumSignal	: Accumlation in/out ref.
sumSQErrors	: Accumulation error in/out ref. Squared value.
sumNEvents	: Accumulation n_event in/out ref.
