## Member Function Documentation

### void sc::SphericalTransformComponentCCA::init (int a, int b, int c, double coef, int pureindex) [inline], [virtual]

Initialize this object. This must be provided in all specializations of this class to establish the ordering between a, b and c and the index of the Cartesian basis function. Other things such as adjustment of the coefficient to account for normalization differences can be done as well. The default **SphericalTransform::init()** implementation requires that only the xl , yl and zl basis functions are normalized to unity.

Implements **sc::SphericalTransformComponent**.
