Member Function Documentation

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

inlinevirtual

Range space of this operator.

Implements Teko::ImplicitLinearOp.

Definition at line 63 of file Teko_DiagnosticLinearOp.hpp.

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

inlinevirtual

Domain space of this operator.

void Teko::DiagnosticLinearOp::implicitApply	(	const MultiVector &	x,
		MultiVector &	y,
		const double	alpha = `1.0`,
		const double	beta = `0.0`
	)		const

virtual

Perform a matrix vector multiply with this operator.

The apply function takes one vector as input and applies the inverse $ LDU $ decomposition. The result is returned in $y$ . If this operator is reprsented as $M$ then $y = \alpha M x + \beta y$ (ignoring conjugation!).

Parameters

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

Implements Teko::ImplicitLinearOp.
