## Public Member Functions

| CorrelationTable (const Ref< PointGroup > &group, const Ref< PointGroup > &subgroup)
| Create a correlation table for the two groups.
Ref< PointGroup > | group () const
| Returns the higher order point group.
Ref< PointGroup > | subgroup () const
| Returns the lower order point group.
int | initialize_table (const Ref< PointGroup > &group, const Ref< PointGroup > &subgroup)
| 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

## Detailed Description

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

## Member Function Documentation

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.

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.
