Detailed Description

The main MueLu adapters (interfaces)

Most applications will use these interfaces to create preconditioners with MueLu. Options are passed to the adapters via Teuchos::ParameterLists or XML input files. Applications can optionally provide nullspace vectors (if known) and/or mesh coordinate vectors (for parallel rebalancing and auxiliary dropping). Adapters are available for Epetra and Tpetra, and return Epetra_Operators and Tpetra::Operators, respectively.
