MultiVector< Scalar, LocalOrdinal, GlobalOrdinal, Node > & Xpetra::MultiVector< Scalar, LocalOrdinal, GlobalOrdinal, Node >::operator= ( const MultiVector< Scalar, LocalOrdinal, GlobalOrdinal, Node > & rhs )

Assignment operator: Does a deep copy.

The assignment operator does a deep copy, just like subclasses' copy constructors.

Note: This currently only works if both *this and the input argument are instances of the same subclass. We do not currently allow assignment between an Xpetra::TpetraMultiVector and an Xpetra::EpetraMultiVector, or vice versa, for example.

		const Vector< Scalar, LocalOrdinal, GlobalOrdinal, Node > &	A,
		const MultiVector< Scalar, LocalOrdinal, GlobalOrdinal, Node > &	B,
		Scalar	scalarThis
	)

pure virtual

Multiply a Vector A elementwise by a MultiVector B.

Compute this = scalarThis * this + scalarAB * B @ A where </tt> denotes element-wise multiplication. In pseudocode, if C denotes *this MultiVector:


C(i,j) = scalarThis * C(i,j) + scalarAB * B(i,j) * A(i,1);

for all rows i and columns j of C.

B must have the same dimensions as *this, while A must have the same number of rows but a single column.

We do not require that A, B, and *this have compatible Maps, as long as the number of rows in A, B, and *this on each process is the same. For example, one or more of these vectors might have a locally replicated Map, or a Map with a local communicator (MPI_COMM_SELF). This case may occur in block relaxation algorithms when applying a diagonal scaling.


Parameters

  
    [in] scalarAB Scaling factor applied to result of elementwise multiplication of A and B 
    [in] A Vector A to be element-wise multiplied with B 
    [in] B MultiVector B to be element-wise multiplied with A 
    [in] scalarThis Scaling factor for existing values in *this<> MultiVector C

protectedpure virtual

Implementation of the assignment operator (operator=); does a deep copy.

Each subclass must implement this. This includes Xpetra::EpetraMultiVector and Xpetra::TpetraMultiVector.

The documentation for this class was generated from the following files:

[in]	scalarAB	Scaling factor applied to result of elementwise multiplication of A and B
[in]	A	Vector A to be element-wise multiplied with B
[in]	B	MultiVector B to be element-wise multiplied with A
[in]	scalarThis	Scaling factor for existing values in `*this<> MultiVector C`
