<p>Hi, <br>
<br>
I am solving a non-linear problem and using a finite difference approximation with coloring to compute the Jacobian matrix.<br>
<br>
</p>
<div>There are several coloring algorithms available in PETSc as indicated here:<br>
https://petsc.org/release/docs/manualpages/Mat/MatColoring.html<br>
<br>
And I was wondering how to switch from one to another in the Jacobian setup routine and also how to check which coloring algorithm I am currently using.<br>
</div>
<br>
<p>Thank you.</p>
