Detailed Description
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.
Member Function Documentation
void sc::CartMolecularCoor::guess_hessian (RefSymmSCMatrix & hessian) [virtual]
Calculate an approximate hessian and place the result in ``hessian''.
RefSymmSCMatrix sc::CartMolecularCoor::inverse_hessian (RefSymmSCMatrix &) [virtual]
Given an Hessian, return the inverse of that hessian. For singular matrices this should return the generalized inverse.
void sc::CartMolecularCoor::save_data_state (StateOut &) [virtual]
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.
virtual int sc::CartMolecularCoor::to_cartesian (RefSymmSCMatrix & cartesian, RefSymmSCMatrix & internal) [virtual]
Convert the internal coordinate Hessian ``internal'' to Cartesian coordinates and copy the result to ``cartesian''. Only the variable internal coordinate force constants are transformed.
virtual int sc::CartMolecularCoor::to_cartesian (RefSCVector & cartesian, RefSCVector & internal) [virtual]
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.
virtual int sc::CartMolecularCoor::to_internal (RefSymmSCMatrix & internal, RefSymmSCMatrix & cartesian) [virtual]
Convert the Cartesian coordinate Hessian ``cartesian'' to internal coordinates and copy the result to ``internal''. Only the variable internal coordinate force constants are calculated.
virtual int sc::CartMolecularCoor::to_internal (RefSCVector & internal, RefSCVector & cartesian) [virtual]
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.
virtual int sc::CartMolecularCoor::to_internal (RefSCVector & internal) [virtual]
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.
