[petsc-dev] How to get rid of the duplicate matrix when using hypre??

[Kong, Fande]

Hi All,

There is a duplicate matrix when using hypre as a preconditioner.  How to
get rid of the duplicate matrix?

I have a PR at
https://bitbucket.org/petsc/petsc/pull-requests/1028/matconvert_aij_hypre-inplace/diff
.

But I am not sure it is the right way to achieve this goal.

Any suggestions are welcome.

Thanks,

Fande,
