<p>How can I obtain the corresponding local matrix from the global matrix? </p>
<p>In my case, the global matrix is of MPIBAIJ type created by <span>DMCreateMatrix(da,MATBAIJ,&A);</span></p></div></div></blockquote><div>Are you asking for unassembled local matrices?</div><div><br></div><div> Thanks,</div><div><br></div><div> Matt <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div id="gmail-m_4284555906601831491divtagdefaultwrapper" style="font-size:12pt;color:rgb(0,0,0);font-family:Calibri,Helvetica,sans-serif" dir="ltr">
