Calculate an approximate hessian and place the result in ``hessian''. virtual RefSymmSCMatrix inverse_hessian (RefSymmSCMatrix &)=0

Given an Hessian, return the inverse of that hessian. virtual int nconstrained ()

Returns the number of constrained coordinates. virtual Ref< NonlinearTransform > change_coordinates ()

When this is called, MoleculeCoor may select a new internal coordinate system and return a transform to it. Ref< SCMatrixKit > matrixkit () const

Ref< Molecule > molecule_

RefSCDimension dnatom3_

Ref< SCMatrixKit > matrixkit_

int debug_

The KeyVal constructor.

molecule

A Molecule object. There is no default.

debug

An integer which, if nonzero, will cause extra output.

matrixkit

A SCMatrixKit object. It is usually unnecessary to give this keyword.

natom3

An SCDimension object for the dimension of the vector of cartesian coordinates. It is usually unnecessary to give this keyword.

When this is called, MoleculeCoor may select a new internal coordinate system and return a transform to it.

The default action is to not change anything and return an IdentityTransform.

Reimplemented in sc::SymmMolecularCoor.

Given an Hessian, return the inverse of that hessian.

For singular matrices this should return the generalized inverse.

Implemented in sc::SymmMolecularCoor, sc::RedundMolecularCoor, and sc::CartMolecularCoor.

Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them.

This must be implemented by the derived class if the class has data.

Reimplemented from sc::SavableState.

Reimplemented in sc::IntMolecularCoor, sc::SymmMolecularCoor, sc::RedundMolecularCoor, and sc::CartMolecularCoor.

Convert the internal coordinate Hessian ``internal'' to Cartesian coordinates and copy the result to ``cartesian''.

Only the variable internal coordinate force constants are transformed.

Implemented in sc::IntMolecularCoor, and sc::CartMolecularCoor.

Convert the internal coordinate gradients in ``internal'' to Cartesian coordinates and copy these Cartesian coordinate gradients to ``cartesian''.

Only the variable internal coordinate gradients are transformed.

Implemented in sc::IntMolecularCoor, and sc::CartMolecularCoor.

Given a set of displaced internal coordinates, update the cartesian coordinates of the Molecule contained herein.

This function does not change the vector ``internal''.

Convert the Cartesian coordinate Hessian ``cartesian'' to internal coordinates and copy the result to ``internal''.

Only the variable internal coordinate force constants are calculated.

Implemented in sc::IntMolecularCoor, and sc::CartMolecularCoor.

Convert the Cartesian coordinate gradients in ``cartesian'' to internal coordinates and copy these internal coordinate gradients to ``internal''.

Only the variable internal coordinate gradients are calculated.

Implemented in sc::IntMolecularCoor, and sc::CartMolecularCoor.

Fill in the vector ``internal'' with the current internal coordinates.

Note that this member will update the values of the variable internal coordinates.

Implemented in sc::IntMolecularCoor, and sc::CartMolecularCoor.
