void PxConstraint::add1stDerivativesToMatrix (  int  idim, double *  M )  const [virtual]

Adds first order derivatives to global covariance matrix M. Parameters: idim  First dimension of array der M  Global covariance matrix, dimension at least idim x idim Reimplemented from ParticleConstraint. Definition at line 57 of file PxConstraint.C. References ParticleConstraint::ConstFitObjectIterator, ParticleConstraint::fitobjects, ParticleFitObject::getDPx(), ParticleConstraint::getGlobalNum(), ParticleFitObject::getGlobalParNum(), ParticleFitObject::getNPar(), and ParticleFitObject::isParamFixed().

void PxConstraint::add2ndDerivativesToMatrix (  int  idim, double *  M, double  lambda )  const [virtual]

Adds second order derivatives to global covariance matrix M. Parameters: idim  First dimension of array der M  Global covariance matrix, dimension at least idim x idim lambda  Lagrange multiplier for this constraint Reimplemented from ParticleConstraint. Definition at line 77 of file PxConstraint.C. References ParticleFitObject::addTo2ndDerivatives(), ParticleConstraint::ConstFitObjectIterator, and ParticleConstraint::fitobjects.

void PxConstraint::getDerivatives (  int  idim, double  der[] )  const [pure virtual]

Get first order derivatives. Call this with a predefined array "der" with the necessary number of entries! Parameters: idim  First dimension of array der der  Array of derivatives, dimension at least idim x idim Implements ParticleConstraint. Definition at line 43 of file PxConstraint.C. References ParticleConstraint::fitobjects.

double PxConstraint::getValue (   )  const [pure virtual]

Returns the value of the constraint. Implements ParticleConstraint. Definition at line 30 of file PxConstraint.C. References ParticleConstraint::fitobjects. Referenced by main().
