If dynamic libraries are used, then the fourth input argument (function)
is ignored.

<H3><FONT COLOR="#CC3333">Sample usage</FONT></H3>
<PRE>
<A HREF="../Mat/MatPartitioningRegisterDynamic.html#MatPartitioningRegisterDynamic">MatPartitioningRegisterDynamic</A>("my_part",/home/username/my_lib/lib/libO/solaris/mylib.a,
"MyPartCreate",MyPartCreate);
</PRE>
<P>
Then, your partitioner can be chosen with the procedural interface via
<pre>
<A HREF="../MatOrderings/MatPartitioningSetType.html#MatPartitioningSetType">MatPartitioningSetType</A>(part,"my_part")
</pre>
or at runtime via the option
<pre>
-mat_partitioning_type my_part
</pre>
<P>
$PETSC_ARCH occuring in pathname will be replaced with appropriate values.
