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.

Public Member Functions inherited from sc::RefCount

Implements sc::NonlinearTransform.

Transform the gradient at a point in the new coordinate system. transform_coordinates must be called first to give the point.

Reimplemented from sc::NonlinearTransform.

Transform the hessian to the new coordinate system. transform_gradient must be called first to initialize this routine.

Reimplemented from sc::NonlinearTransform.

Transform the inverse of the hessian. transform_gradient must be called first to initialize this routine.
