[petsc-users] [petsc-3.2] MatView on dense matrix

[Barry Smith]

   The problem is from the C values of these parameters have gotten out of sync with the Fortran values.

    Satish,

     Could you please fix the finclude/petscviewer.h values to match the C in petsc-3.2 and send a patch?

     Thanks

     Barry
