Detailed Description
The NonlinearTransform class transforms between two nonlinear coordinate systems.
It is needed when a change of coordinates occurs in the middle of an optimization.
Member Function Documentation
virtual void sc::NonlinearTransform::transform_coordinates (const RefSCVector & x) [pure virtual]
Transform the coordinates.
Implemented in sc::IdentityTransform.
virtual void sc::NonlinearTransform::transform_gradient (const RefSCVector & g) [virtual]
Transform the gradient at a point in the new coordinate system. transform_coordinates must be called first to give the point.
Reimplemented in sc::IdentityTransform.
virtual void sc::NonlinearTransform::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 in sc::IdentityTransform.
virtual void sc::NonlinearTransform::transform_ihessian (const RefSymmSCMatrix & ih) [virtual]
Transform the inverse of the hessian. transform_gradient must be called first to initialize this routine.
Reimplemented in sc::IdentityTransform.
