Member Function Documentation

double RootResidualFunction::DataElement	(	const double *	pars,
		unsigned int	index,
		double *	gradients = `0`
	)		const

override

Evaluation of single data element residual. Will be called by ROOT minimizer.

Returns residual value for given data element index.

Transform call of ancient pointer based function to safer gradient_function_t.

Parameters

pars	array of fit parameter values from the minimizer
index	index of residual element
gradients	if not zero, then array where we have to put gradients
