Member Function Documentation

virtual VectorSpace Teko::BlockImplicitLinearOp::range ( ) const [pure virtual]

Range space of this operator.

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

virtual VectorSpace Teko::BlockImplicitLinearOp::domain ( ) const [pure virtual]

Domain space of this operator.

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

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 $y$ . If this operator is reprsented as $M$ then $y = \alpha M x + \beta y$

Parameters:

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

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

bool Teko::BlockImplicitLinearOp::opSupportedImpl ( const Thyra::EOpTransp M_trans ) const [protected, virtual]

Functions required by Thyra::LinearOpBase.
