[petsc-users] SuperLU options database

[Su Yan]

Hi, I am trying to use the external package SuperLU to solve a linear
equation with ILUTP preconditioner. But the current PETSc only provides one
option interface which is MatSuperluSetILUDropTol. There are actually many
other options as suggested on the manual page of MATSOLVERSUPERLU, such as:

*-mat_superlu_equil*
*-mat_superlu_ilu_filltol*
*-**mat_superlu_ilu_fillfactor*

etc. However, they all need to be invoked via command line.

Is there any way to set up other options for SuperLU in the code instead of
using the command line? Because it's not so convenient to type in all those
runtime commands every time you run a code.

Thanks a lot.

Su
