I remember similar question has been asked long time ago, but I can not
If I set MatSetOption(A,MAT_SYMMETRIC,PETSC_TRUE), does PETSc take this
into account when doing MatMult or similar operations?
As far as I can see it does not (I'm not sure I look at the right place
though). Could it really save time in principle?
