<div style="line-height:1.7;color:#000000;font-size:14px;font-family:arial"><P>Hello,</P>
<P> I want to determine the positive definiteness. So I want to know</P>
<P>if it is a right way.</P>
<P> I use "-ksp_type cg -pc_type none". You know, CG does not work for</P>
<P>indefinite matrices. I get "Linear solve did not converge due to </P>
<P>DIVERGED_INDEFINITE_MAT". From the information, I think it is indefinite.</P>
<P>Is it a right way?</P>
<P> Thanks.</P>
<P> Jim</P>
