◆ apply() [1/2]

virtual void AMP::Operator::LinearOperator::apply	(	AMP::LinearAlgebra::Vector::const_shared_ptr	u,
		AMP::LinearAlgebra::Vector::shared_ptr	f
	)

overridevirtualinherited

The apply function for this operator, A, performs the following operation: f = A(u) Here, A(u) is simply a Matrix-Vector multiplication.

Parameters

[in]	u	input vector.
[out]	f	residual/output vector.
