Xpetra-specific matrix class.
This class is specific to Xpetra and has no analogue in Epetra or Tpetra. The main motivation for this class is to be able to access matrix data in a manner different than how it is stored. For example, it might be more convenient to treat ("view") a matrix stored in compressed row storage as if it were a block matrix. The Xpetra::Matrix class is intended to manage these "views".

Multiplies this matrix by a MultiVector.
\c X is required to be post-imported, i.e., described by the column map of the matrix. \c Y is required to be pre-exported, i.e., described by the row map of the matrix.
Both are required to have constant stride, and they are not permitted to ocupy overlapping space. No runtime checking will be performed in a non-debug build.
This method is templated on the scalar type of MultiVector objects, allowing this method to be applied to MultiVector objects of arbitrary type. However, it is recommended that multiply() not be called directly; instead, use the CrsMatrixMultiplyOp, as it will handle the import/exprt operations required to apply a matrix with non-trivial communication needs.
If beta is equal to zero, the operation will enjoy overwrite semantics (Y will be overwritten with the result of the multiplication). Otherwise, the result of the multiplication will be accumulated into Y.Implements DistObject interface Access function for the Tpetra::Map this DistObject was constructed with.
