evalDirect()

void ALinearOpMulti::evalDirect	(	const VectorVectorDouble &	inv,
		VectorVectorDouble &	outv
	)		const

Evaluate the product: 'outv' = Q * 'inv'

Parameters

[in]	inv	Array of input values
[out]	outv	Array of output values

evalInverse()

void ALinearOpMulti::evalInverse ( const VectorVectorDouble &  vecin, VectorVectorDouble &  vecout  ) const

virtual

Evaluate the product: 'outv' = Q^{-1} * 'inv' by conjugate gradient

Parameters

[in]	vecin	Array of input values
[out]	vecout	Array of output values. Will be used as initial value if _userInitialValue is true.

Reimplemented in PrecisionOpMultiConditionalCs.

const

This method intends to resize the different working arrays. It is considered as const in order to avoid breaking constness of calling function

setEps()

void ALinearOpMulti::setEps ( double  eps )

inline

setNIterMax()

void ALinearOpMulti::setNIterMax ( int  nitermax )

inline

setPrecond()

void ALinearOpMulti::setPrecond	(	const ALinearOpMulti *	precond,
		int	status
	)

Define the Pre-Conditioner facility

Parameters

[in]	precond	Pointer to a ALinearOp operator
[in]	status	Status of this Pre-conditioner 0 : not defined and therefore not used -1 : Pre-conditioner is the Q_{-1} 1 : Pre-conditioner is the Q

Remarks

When 'precond' argument is not provided, 'status' is forced to 0

size()

virtual int ALinearOpMulti::size ( int  ) const

pure virtual

Implemented in PrecisionOpMultiConditional.

sizes()

virtual int ALinearOpMulti::sizes ( ) const

pure virtual

Implemented in PrecisionOpMultiConditional.
