Dear Jed,<br><br>I am taking a look at ex15 (<a href="http://www.mcs.anl.gov/petsc/petsc-current/src/mat/examples/tutorials/ex15.c.html">http://www.mcs.anl.gov/petsc/petsc-current/src/mat/examples/tutorials/ex15.c.html</a>).<br>
I am very confused with this. In Section 3.5 Partitioning of the manual, one special Mat, that is 'adj', need to be established. <br>However, in ex15, the common matrix is created. Does the matrix automatically contain the connection information? <br>
<br>Thanks a lot,<br>Yujie<br><br><div class="gmail_quote">On Mon, Feb 20, 2012 at 4:45 PM, Jed Brown <span dir="ltr"><<a href="mailto:jedbrown@mcs.anl.gov">jedbrown@mcs.anl.gov</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

It is not only redistribute the matrix. I want to get the reorder information and use matpermute to reorder the matrix.</blockquote></div><br></div><div>MatConvert().</div><div><br></div><div>ISPartitioningToNumbering() might also be useful for you.</div>
