◆ setParameters()

		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
