 Returns the solid harmonic basis function index of component i.

double coef (int i) const
 Returns the transform coefficient of component i.

int a (int i) const
 Returns the Cartesian basis function's x exponent of component i.

int b (int i) const
 Returns the Cartesian basis function's y exponent of component i.

int c (int i) const

Detailed Description

This is a base class for a container for a sparse Cartesian to solid harmonic basis function transformation.


Constructor & Destructor Documentation

sc::SphericalTransform::SphericalTransform int    l,
int    subl = -1
[protected]
 

This constructs the SphericalTransform for the given Cartesian angular momentum l and solid harmonic angular momentum subl.

Usually, l and subl will be the same. They would differ when the S component of a D Cartesian shell or the P component of an F Cartesian shell is desired, for example (see the natural atomic orbital code for an example of such use). The init member must be called to complete initialization.


Member Function Documentation

virtual void sc::SphericalTransform::init   [protected, virtual]
 

This determines all of the components of the transformation.

It should be possible to implement the SphericalTransformComponent::init specialization in such a way that the default SphericalTransform::init can be used.

Reimplemented in sc::ISphericalTransform.
