Note: these correspond to the optional final arguments passed to <A HREF="../DMDA/DMDACreate.html#DMDACreate">DMDACreate</A>(), <A HREF="../DMDA/DMDACreate2d.html#DMDACreate2d">DMDACreate2d</A>(), <A HREF="../DMDA/DMDACreate3d.html#DMDACreate3d">DMDACreate3d</A>()
<P>
In Fortran one must pass in arrays lx, ly, and lz that are long enough to hold the values; the sixth, seventh and
eighth arguments from <A HREF="../DMDA/DMDAGetInfo.html#DMDAGetInfo">DMDAGetInfo</A>()
<P>
In C you should not free these arrays, nor change the values in them. They will only have valid values while the
<A HREF="../DMDA/DMDA.html#DMDA">DMDA</A> they came from still exists (has not been destroyed).
<P>
These numbers are NOT multiplied by the number of dof per node.
