sc::IdentityTransform(3) MPQC sc::IdentityTransform(3) NAME sc::IdentityTransform - The IdentityTransform is a special case of Nonlin- earTransform were no transformation takes place. SYNOPSIS #include <transform.h> Inherits sc::NonlinearTransform. Public Member Functions void transform_coordinates (const RefSCVector &x) These override the tranformation members of NonlinearTransform and do nothing. void transform_gradient (const RefSCVector &g) Transform the gradient at a point in the new coordinate system. void transform_hessian (const RefSymmSCMatrix &h) Transform the hessian to the new coordinate system. void transform_ihessian (const RefSymmSCMatrix &ih) Transform the inverse of the hessian. virtual void transform_coordinates (const RefSCVector &x)=0 Transform the coordinates. virtual void transform_gradient (const RefSCVector &g) Transform the gradient at a point in the new coordinate system. virtual void transform_hessian (const RefSymmSCMatrix &h) Transform the hessian to the new coordinate system. virtual void transform_ihessian (const RefSymmSCMatrix &ih) Transform the inverse of the hessian. Public Member Functions inherited from sc::RefCount int lock_ptr () const Lock this object. int unlock_ptr () const Unlock this object. void use_locks (bool inVal) start and stop using locks on this object refcount_t nreference () const Return the reference count. refcount_t reference () Increment the reference count and return the new count. refcount_t dereference () Decrement the reference count and return the new count. int managed () const void unmanage () Turn off the reference counting mechanism for this object. int managed () const Return 1 if the object is managed. Otherwise return 0. Public Member Functions inherited from sc::Identity Identifier identifier () Return the Identifier for this argument.

Member Function Documentation void sc::IdentityTransform::transform_coordinates (const RefSCVector & x) [virtual] These override the tranformation members of NonlinearTransform and do noth- ing. Implements sc::NonlinearTransform. void sc::IdentityTransform::transform_gradient (const RefSCVector & g) [vir- tual] Transform the gradient at a point in the new coordinate system. trans- form_coordinates must be called first to give the point. Reimplemented from sc::NonlinearTransform. void sc::IdentityTransform::transform_hessian (const RefSymmSCMatrix & h) [virtual] Transform the hessian to the new coordinate system. transform_gradient must be called first to initialize this routine. Reimplemented from sc::NonlinearTransform. void sc::IdentityTransform::transform_ihessian (const RefSymmSCMatrix & ih) [virtual] Transform the inverse of the hessian. transform_gradient must be called first to initialize this routine. Reimplemented from sc::NonlinearTransform. Author Generated automatically by Doxygen for MPQC from the source code. Version 2.3.1 Thu Sep 3 2026 sc::IdentityTransform(3)
