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.
