[Trilinos-Users] BELOS + GMRES + ML (preconditioner)

Dear all,

I am using Trilinos 12.10.1. I want to use GMRES as a solver from BELOS
with Multigrid (ML) as a preconditioner for solving linear system of
equations. My linear system is

Ax = b

where, A is Epetra_CRS matrix, and x and b are Epetra vectors. My numerical
code is based on Epetra (not Tpetra).

Can you please provide some example code?

Many thanks in advance,
Deepak Garg
