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_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.
