Constructor & Destructor Documentation

template<class T> vnl_scalar_join_iterator< T >::vnl_scalar_join_iterator (  const vnl_matrix< T > &    relation1, unsigned    column1, const vnl_matrix< T > &    relation2, unsigned    column2 )

Initialize this iterator to the join of. relation1(:,column1) and relation2(:,column2). The algorithm sorts an array of pointers to each row and traversal of the iterator runs through these to produce the join. After construction the row1() and row2() methods indicate the first pair.
