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 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 IdentityTransform.

virtual void 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 IdentityTransform.

virtual void 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 IdentityTransform.
