What is IFPACK?

IFPACK provides a suite of object-oriented algebraic preconditioners for the solution of preconditioned iterative solvers. IFPACK constructors expect an Epetra_RowMatrix object for construction. IFPACK is part of the Trilinos Solver Project and IFPACK object interact well with other Trilinos classes. In particular, IFPACK can be used as a preconditioner for AztecOO. Top
