[petsc-users] How to call MUMPS for general symmetric matrix?

Dear PETSc dev team,
   I have a general symmetric matrix which I want to call MUMPS symbolic to
get memory estimate. I see MatLUFactorSymbolic and MatCholeskyFactor but
there is no API for general symmetric. In MUMPS there are three types SYM:
0 unsymmetric; 1: symmetric positive definite; 2: general symmetric. I am
wondering if PETSc API is missing or if I am missing something.

Thanks,
Sam
