<br>
I'd like to know is there a function in Petsc or in Slepc for calculating the <br>
LTL^T decomposition?<br>
<br>
Aside from that If I want to perform the rows and column reordering which function <br>
or function set should I use in Petsc? I haven't see any vector extraction <br>
from matrices on the manual. <br>
<br>
How can I perform the gauss elimination method in Petsc?<br></blockquote><div><br></div><div><a href="http://www.mcs.anl.gov/petsc/petsc-dev/docs/linearsolvertable.html">http://www.mcs.anl.gov/petsc/petsc-dev/docs/linearsolvertable.html</a><br>
