void EConstraint::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 58 of file EConstraint.C. References ParticleConstraint::ConstFitObjectIterator, ParticleConstraint::fitobjects, ParticleFitObject::getDE(), ParticleConstraint::getGlobalNum(), ParticleFitObject::getGlobalParNum(), ParticleFitObject::getNPar(), and ParticleFitObject::isParamFixed().

void EConstraint::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.
