void sc::DerivCenters::add_center (int center, int atom)

Add a center using the atom number. Parameters:

center The center number (between 0 and 3 inclusive).
atom The center within a GaussianBasisSet.

void sc::DerivCenters::add_center (int center, const Ref< GaussianBasisSet > & bs, int shell)

Add a center using a basis set and the shell number. Parameters:

center The center number (between 0 and 3 inclusive).
bs The basis set for this center.
shell The shell number for this center.

void sc::DerivCenters::add_omitted (int center, int atom)

Add the omitted center using the atom number. Parameters:

center The center number (between 0 and 3 inclusive).
atom The center within a GaussianBasisSet.

void sc::DerivCenters::add_omitted (int center, const Ref< GaussianBasisSet > & bs, int shell)

Add the omitted center using a basis set and the shell number. Parameters:

center The center number (between 0 and 3 inclusive).
bs The basis set for this center.
shell The shell number for this center.

int sc::DerivCenters::atom (int i) const [inline]Parameters:

i The computed center index (between 0 and n() - 1, inclusive).

Returns:

The atom number.

Referenced by sc::LocalTBGrad< T >::run().

int sc::DerivCenters::center (int i) const [inline]Parameters:

i The computed center index (between 0 and n() - 1, inclusive).

Returns:

The center number (between 0 and 3, inclusive).

int sc::DerivCenters::has_omitted_center () const [inline]Returns:

1 if there is an omitted center, otherwise 0.
