## 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.
