Detailed Description

CartesianIter gives the ordering of the Cartesian functions within a shell for the particular integrals specialization.

Member Function Documentation

◆ bfn()

int sc::CartesianIter::bfn ( )
inline

Returns the number of the current basis function within the shell.

This starts at 0 and sequentially increases as next() is called.
