Fwd: [petsc-users] MatZeroRows and MATELEMENTAL

[Matthew Knepley]

I do not know the answer to this one. Is there something in that does the equivalent of

MatZeroRows(), or do you do it by hand?

  Thanks,

Dear PETSc users,

I have a code for PETSc 3.3 in which the PLAPACK interface, now discontinued, was used. I am trying to update it to PETSc 3.5.2, using the Elemental interface. 

I see that MatZeroRows is not implemented for MATELEMENTAL. What function should I use instead? Does it also support the version with optional arguments x and b?

Thanks,

best regards,

Francesco
