<A HREF="../Mat/MatSetValues.html#MatSetValues">MatSetValues</A>() generally caches the values.  The matrix is ready to
use only after <A HREF="../Mat/MatAssemblyBegin.html#MatAssemblyBegin">MatAssemblyBegin</A>() and <A HREF="../Mat/MatAssemblyEnd.html#MatAssemblyEnd">MatAssemblyEnd</A>() have been called.
Use <A HREF="../Mat/MatAssemblyType.html#MatAssemblyType">MAT_FLUSH_ASSEMBLY</A> when switching between <A HREF="../Sys/ADD_VALUES.html#ADD_VALUES">ADD_VALUES</A> and <A HREF="../Sys/INSERT_VALUES.html#INSERT_VALUES">INSERT_VALUES</A>
in <A HREF="../Mat/MatSetValues.html#MatSetValues">MatSetValues</A>(); use <A HREF="../Mat/MatAssemblyType.html#MatAssemblyType">MAT_FINAL_ASSEMBLY</A> for the final assembly before
using the matrix.
<P>
Space for preallocated nonzeros that is not filled by a call to <A HREF="../Mat/MatSetValues.html#MatSetValues">MatSetValues</A>() or a related routine are compressed
out by assembly. If you intend to use that extra space on a subsequent assembly, be sure to insert explicit zeros
before <A HREF="../Mat/MatAssemblyType.html#MatAssemblyType">MAT_FINAL_ASSEMBLY</A> so the space is not compressed out.
<P>
