Hi all,<br>
<br>
I just come into this question: if one wants a sub-vector with contiguous indices<br>
in the whole vector, surely, one can use getsubvec, but also one can setup a<br>
sparse boolean matrix for this aim; so which method is better, considering<br>
the whole vector is local or parallel?<br></blockquote><div><br></div><div><a href="http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-current/docs/manualpages/Vec/VecScatterCreate.html">http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-current/docs/manualpages/Vec/VecScatterCreate.html</a></div>
