Initalize the correlation table.
const char * error (int errcod)
Converts error codes from initialize_table into a text string.
int n () const
Returns the number of irreps in the high order group.
int subn () const
Returns the number of irreps in the subgroup.
int degen (int igamma) const
Returns the degeneracy of the irrep.
int subdegen (int igamma) const
Returns the degeneracy of the subgroup irrep.
int ngamma (int igamma) const
Returns the number of irreps in the low order group that an irrep.
int gamma (int igamma, int i) const
Returns the irreps in the low order group that an irrep from the high order group can be reduced to.

Detailed Description

The CorrelationTable class provides a correlation table between two point groups.

Member Function Documentation

int sc::CorrelationTable::gamma (int igamma, int i) const [inline]

Returns the irreps in the low order group that an irrep from the high order group can be reduced to.

int sc::CorrelationTable::initialize_table (const Ref< PointGroup > & group, const Ref< PointGroup > & subgroup)

Initalize the correlation table. Returns 0 for success and nonzero for failure. This will fail if the subgroup is not really a subgroup of group.
