AZOO_iterate: A function built around AztecOO that mimics the Aztec funciton AZ_iterate.
AZOO_iterate is intended to facilitate the smooth transition from Aztec to Trilinos/AztecOO. The AZOO_iterate interface is essentially identical to the AZ_iterate interface and should be, for most uses a simple replacement in functionality. However, because AztecOO uses Petra for distributed matrix and vector services (instead of AZ_MATRIX as defined by Aztec), there will be some differences. Some known differences are: <ol> <li> AZOO_iterate does not support Aztec's matrix-free version of AZ_MATRIX at this time. Note that AztecOO has its own version of matrix-free implementation via the pure virtual class Epetra_RowMatrix. <li> Scaling is performed independently in AztecOO. All of the Aztec scaling options (options[AZ_scaling]) are recognized, but block Jacobi scaling is implemented as point Jacobi scaling. <li> Block entry preconditioners are not supported in AztecOO. This functionality will be provided by IFPACK in a future release. </ol>
