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
◆ transform_gradient()
|
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.
◆ transform_hessian()
|
virtual |
Transform the hessian to the new coordinate system.
transform_gradient must be called first to initialize this routine.
Reimplemented in sc::IdentityTransform.
◆ transform_ihessian()
|
virtual |
Transform the inverse of the hessian.
transform_gradient must be called first to initialize this routine.
Reimplemented in sc::IdentityTransform.
