Detailed Description

template<class TupleType, int NTRK>
class CombinedKinematicConstraintT< TupleType, NTRK >

This class combines several user defined constraints (by expanding the vector d and the matrices D and E). Usage: Add each constraint to a std::tuple<MultiTrackKinematicConstraint..... >. This tuple has to be used in the constructor:

The produced object can be used by KinematicConstrainedVertexFitter.fit()
