Methods implementing Matrix

Multiplies this matrix by a MultiVector.

X is required to be post-imported, i.e., described by the column map of the matrix. 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.

virtual void apply (const MultiVector &X, MultiVector &Y, Teuchos::ETransp mode=Teuchos::NO_TRANS, Scalar alpha=ScalarTraits< Scalar >::one(), Scalar beta=ScalarTraits< Scalar >::zero()) const

const ArrayView< const GlobalOrdinal > &  cols,
const ArrayView< const Scalar > &  vals 
)
inlinevirtual

Insert matrix entries, using global IDs.

Note: this routine throws for Rows() > 1 and/or Cols() > 1

All index values must be in the global space.

Precondition
globalRow exists as an ID in the global row map
isLocallyIndexed() == false
isStorageOptimized() == false
Postcondition
isGloballyIndexed() == true
Note
If globalRow does not belong to the matrix on this node, then it will be communicated to the appropriate node when globalAssemble() is called (which will, at the latest, occur during the next call to fillComplete().) Otherwise, the entries will be inserted in the local matrix.
If the matrix row already contains values at the indices corresponding to values in cols, then the new values will be summed with the old values; this may happen at insertion or during the next call to fillComplete().
If hasColMap() == true, only (cols[i],vals[i]) where cols[i] belongs to the column map on this node will be inserted into the matrix.

Replace matrix entries, using global IDs.

All index values must be in the global space.

Precondition
globalRow is a global row belonging to the matrix on this node.
Note
If (globalRow,cols[i]) corresponds to an entry that is duplicated in this matrix row (likely because it was inserted more than once and fillComplete() has not been called in the interim), the behavior of this function is not defined.

) const
inlinevirtual

Extract a list of entries in a specified local row of the matrix. Put into storage allocated by calling routine.

Parameters
LocalRow- (In) Local row number for which indices are desired.
Indices- (Out) Local column indices corresponding to values.
Values- (Out) Matrix values.
NumIndices- (Out) Number of indices.

Note: A std::runtime_error exception is thrown if either Indices or Values is not large enough to hold the data associated with row LocalRow. If LocalRow is not valid for this node, then Indices and Values are unchanged and NumIndices is returned as OrdinalTraits<size_t>::invalid().

Precondition
isLocallyIndexed()==true or hasColMap() == true

Special multiplication routine (for BGS/Jacobi smoother)

Computes the sparse matrix-multivector multiplication (plus linear combination with input/result vector)

Performs $Y = \alpha A^{\textrm{mode}} X + \beta Y$, with one special exception:

  • if beta == 0, apply() overwrites Y, so that any values in Y (including NaNs) are ignored.
  • calculates result only for blocked row "row"
  • useful for BGS/Jacobi smoother in MueLu: there we have to calculate the residual for the current block row we can skip the MatVec calls in all other block rows
Parameters
XVector to be multiplied by matrix (input)
Yresult vector
rowIndex of block row to be treated
modeTranspose mode
alphascaling factor for result of matrix-vector product
betascaling factor for linear combination with result vector

inlineprivate

Add a Xpetra::CrsMatrix to another: B = B*scalarB + A*scalarA.

Note, that this routine works only correctly if A only has entries which are empty (zero) in B. We use the insertGlobalValues routine for inserting the new values from A in B. The sumIntoGlobalValues routine is not implemented in Xpetra (and would not extend the graph of B for new entries). Here we need something to catch the exceptions of a future implementation of sumIntoGlobalValues that then adds the remaining new entries with insertGlobal Values.

This routine is private and used only by Merge. Since the blocks in BlockedCrsMatrix are seperated, this routine works for merging a BlockedCrsMatrix.
