<div><br>
</div>
<div>one quick question: I have a matrix P and need to compute P^t*P.</div>
<div>Is there a function available for this? I couldn't find anything.</div>
<div>Right now I am computing P^t*P by using MatPtAP with A=identity,</div>
<div>but I was hoping there is another way where I don't need to set up</div>
<div>the identity matrix.</div>
</div>

</div>
<div>Use petsc-dev and MatTransposeMatMult(P,P,...,&PtP)</div>
