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

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.

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.

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.
