derivatives()

const AlgebraicMatrix& TkFittedLasBeam::derivatives ( void  ) const

inline

matrix of local derivatives: columns are parameters, rows are hits

firstFixedParameter()

unsigned int TkFittedLasBeam::firstFixedParameter ( ) const

inline

index of first parameter and its derivative that was not fixed in the fit, but might be free in a global fit, e.g. within millepede

setParameters()

void TkFittedLasBeam::setParameters	(	unsigned int	parametrisation,
		const std::vector< Scalar > &	params,
		const AlgebraicSymMatrix &	paramCovariance,
		const AlgebraicMatrix &	derivatives,
		unsigned int	firstFixedParam,
		float	chi2
	)

set parameterisation (0=undefined), derivatives, chi^2 etc:

• 'params' and 'derivatives' must be parallel,
• 'covariance' contains the free part, i.e. has size 'firstFixedParam'
• obeye firstFixedParam <= params.size() throws if inconsistent
