NAME

       sc::SpatialMOPairIter_neq - SpatialMOPairIter_neq gives the ordering of pairs of spatial
       orbitals from different spaces.

SYNOPSIS

       #include <pairiter.h>

       Inherits sc::SpatialMOPairIter.

   Public Member Functions
       SpatialMOPairIter_neq (const Ref< MOIndexSpace > &space1, const Ref< MOIndexSpace >
           &space2)
           Initialize an iterator for the given MO spaces.
       void start (const int ij_offset=0)
           Initialize the iterator assuming that iteration will start with pair ij_offset.
       void next ()
           Move to the next pair.
       operator int () const
           Returns nonzero if the iterator currently hold valid data.
       int nij_aa () const
           Returns the number of functions in alpha-alpha space.
       int nij_ab () const
           Returns the number of functions in alpha-beta space.
       int ij_aa () const
           Returns compound index ij for alpha-alpha case.
       int ij_ab () const
           Returns compound index ij for alpha-beta case.
       int ij_ba () const
           Returns compound index ij for beta-alpha case.

Detailed Description

       SpatialMOPairIter_neq gives the ordering of pairs of spatial orbitals from different
       spaces.

       It iterates over all ij combinations (total of ni_*nj_ pairs).
