[petsc-users] About MatMumpsSetIcntl function

[김성익]

Hello,


I tried to adopt METIS option in MUMPS by using
' PetscCall(MatMumpsSetIcntl(Mat, 7, 5));'

However, there is an error as follows

[0]PETSC ERROR: Object is in wrong state
[0]PETSC ERROR: Only for factored matrix
[0]PETSC ERROR: See https://petsc.org/release/faq/ for trouble shooting.
[0]PETSC ERROR: Petsc Release Version 3.18.1, unknown

[0]PETSC ERROR: #2 main() at /home/ksi2443/Downloads/coding/a1.c:149
[0]PETSC ERROR: No PETSc Option Table entries

How can I fix this error?

Thank you for your help.
