Member Function Documentation

range()

virtual VectorSpace Teko::BlockImplicitLinearOp::range ( ) const

pure virtual

Range space of this operator.

Implemented in Teko::BlockDiagonalInverseOp, Teko::BlockLowerTriInverseOp, Teko::BlockUpperTriInverseOp, Teko::LU2x2InverseOp, and Teko::MultPrecsLinearOp.

domain()

virtual VectorSpace Teko::BlockImplicitLinearOp::domain ( ) const

pure virtual

Domain space of this operator.

Implemented in Teko::BlockDiagonalInverseOp, Teko::BlockLowerTriInverseOp, Teko::BlockUpperTriInverseOp, Teko::LU2x2InverseOp, and Teko::MultPrecsLinearOp.

implicitApply() [1/2]

virtual void Teko::BlockImplicitLinearOp::implicitApply ( const BlockedMultiVector & x, BlockedMultiVector & y, const double alpha = 1.0, const double beta = 0.0 ) const

pure virtual

Perform a matrix vector multiply with this implicitly defined blocked operator.

The apply function takes one vector as input and applies a linear operator. The result is returned in . If this operator is reprsented as then

Parameters

[in]	x
[in,out]	y
[in]	alpha	(default=1)
[in]	beta	(default=0)

Implemented in Teko::BlockDiagonalInverseOp, Teko::BlockLowerTriInverseOp, Teko::BlockUpperTriInverseOp, Teko::LU2x2InverseOp, and Teko::MultPrecsLinearOp.

implicitApply() [2/2]

void Teko::BlockImplicitLinearOp::implicitApply ( const Thyra::EOpTransp M_trans, const BlockedMultiVector & x, BlockedMultiVector & y, const double alpha = 1.0, const double beta = 0.0 ) const

virtual

Perform a matrix vector multiply with this implicitly defined blocked operator.

The apply function takes one vector as input and applies a linear operator. The result is returned in . If this operator is reprsented as then

Parameters

[in]	x
[in,out]	y
[in]	alpha	(default=1)
[in]	beta	(default=0)

Reimplemented in Teko::BlockDiagonalInverseOp, Teko::BlockLowerTriInverseOp, Teko::BlockUpperTriInverseOp, Teko::LU2x2InverseOp, and Teko::MultPrecsLinearOp.
