#!CSeaGreen #!N #!Rcotas Creating Positions
and Connections Grids #!N #!EC #!N #!N Compact Arrays allow compact
encoding of positions and connections. Four subclasses of Arrays represent 1-
and multidimensional regular positions and connections: #!T,1,216,431,646 #!F-adobe-times-bold-r-normal--18* #!N TAB -
TAB positions TAB connections #!EF #!N TAB One-dimensional TAB RegularArray TAB
PathArray #!N TAB n-dimensional TAB ProductArray TAB MeshArray #!N #!N In
addition, the subclass Constant Array allows compact encoding of a constant
value of any type, category, rank, or shape. #!N #!N For
more information about compact Array Objects, see #!Ldatmod,dxall197 h Understanding the Data Model #!EL in IBM Visualization
Data Explorer User's Guide. #!CIndianRed #!N #!N #!N #!F-adobe-times-bold-r-normal--18* Note on
Use #!N #!N The generic routine #!F-adobe-times-bold-r-normal--18* DXGetArrayData() #!EF expands the
data of a compact Array into an explicitly indexed array and
is the preferred means for this purpose. However, it is better
still to code your algorithm so that no expansion of the
Array is performed. #!N #!N #!EC #!N #!N In addition to
the low-level routines for creating various compact Arrays (described later), Data
Explorer provides the following higher-level routines for creating a regular grid
of positions or connections. These routines are to be preferred when
there is a choice, because most Data Explorer functions support regular
grids of positions or connections efficiently. #!N #!I0 #!N #!N #!I0
