Protected Member Functions inherited from sc::RefCount
RefCount (const RefCount &)
RefCount & operator= (const RefCount &)

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.

Returns a smart reference to an SCDimension equal to the number of coordinates (be they Cartesian, internal, or whatever) that are being optimized.

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

Calculate an approximate hessian and place the result in “hessian”.

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

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.

Returns the number of constrained coordinates.

Reimplemented in sc::IntMolecularCoor.

Print the coordinate.

Reimplemented from sc::DescribedClass.

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

Given a set of displaced internal coordinates, update the cartesian coordinates of the Molecule contained herein. This function does not change the vector “internal”.

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

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

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