sc::identitytransform(3)

NAME

sc::IdentityTransform - The IdentityTransform is a special case of NonlinearTransform were no transformation takes place.

SYNOPSIS

#include <transform.h>
Inherits sc::NonlinearTransform.
Public Member Functions
void transform_coordinates (const RefSCVector &x)
    These override the tranformation members of NonlinearTransform and
    do nothing.
void transform_gradient (const RefSCVector &g)
    Transform the gradient at a point in the new coordinate system.
void transform_hessian (const RefSymmSCMatrix &h)
    Transform the hessian to the new coordinate system.
void transform_ihessian (const RefSymmSCMatrix &ih)
    Transform the inverse of the hessian.

Detailed Description

The IdentityTransform is a special case of NonlinearTransform were no transformation takes place.

Member Function Documentation

void sc::IdentityTransform::transform_coordinates (const RefSCVector & x)

[virtual]
These override the tranformation members of NonlinearTransform and do nothing.

Implements sc::NonlinearTransform.

void sc::IdentityTransform::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 from sc::NonlinearTransform.

void sc::IdentityTransform::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 from sc::NonlinearTransform.

void sc::IdentityTransform::transform_ihessian (const RefSymmSCMatrix & ih)

[virtual]
Transform the inverse of the hessian.

transform_gradient must be called first to initialize this routine.

Reimplemented from sc::NonlinearTransform.
