LOBPCGEpetraExGenPrecIfpack.cpp

Use LOBPCG with Epetra and Ifpack preconditioner.

Use LOBPCG with Epetra and Ifpack preconditioner.This example computes the eigenvalues of largest magnitude of an generalized eigenvalue problem, using Anasazi's implementation of the LOBPCG method, with Epetra linear algebra. It preconditions LOBPCG with an Ifpack incomplete Cholesky preconditioner.
