The CartMolecularCoor class implements Cartesian coordinates in a way suitable for use in geometry optimizations.

CartMolecularCoor is a SavableState has StateIn and KeyVal constructors. CartMolecularCoor is derived from MolecularCoor.

These implement the virtual functions inherited from MolecularCoor.

Implements sc::MolecularCoor.

Calculate an approximate hessian and place the result in ``hessian''.

Implements sc::MolecularCoor.

Given an Hessian, return the inverse of that hessian. For singular matrices this should return the generalized inverse.

Implements sc::MolecularCoor.

Print the coordinate.

Implements sc::MolecularCoor.

Implements sc::MolecularCoor.

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::MolecularCoor.

Implements sc::MolecularCoor.

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.

Implements sc::MolecularCoor.

Convert the internal coordinate Hessian internal'' to Cartesian coordinates and copy the result tocartesian''. Only the variable internal coordinate force constants are transformed.

Implements sc::MolecularCoor.

Fill in the vector ``internal'' with the current internal coordinates. Note that this member will update the values of the variable internal coordinates.

Implements sc::MolecularCoor.

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.

Implements sc::MolecularCoor.

Convert the Cartesian coordinate Hessian cartesian'' to internal coordinates and copy the result tointernal''. Only the variable internal coordinate force constants are calculated.

Implements sc::MolecularCoor.
