[petsc-users] MatColoring

[Jorti, Zakariae]

Hi,

I am solving a non-linear problem and using a finite difference approximation with coloring to compute the Jacobian matrix.


There are several coloring algorithms available in PETSc as indicated here:
https://petsc.org/release/docs/manualpages/Mat/MatColoring.html

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.


Thank you.
