Member Function Documentation

template<class Real>

virtual void ROL::RangeSpaceOperator< Real >::update	(	const Vector< Real > &	x,
		bool	flag = `true`,
		int	iter = `-1`
	)

inlinevirtual

Update linear operator.

This function updates the linear operator at new iterations.

Parameters

[in]	x	is the new iterate.
[in]	flag	is true if the iterate has changed.
[in]	iter	is the outer algorithm iterations count.

Reimplemented from ROL::LinearOperator< Real >.

		const Vector< Real > &	v,
		Real &	tol
	)		const

inlinevirtual

Apply linear operator.

This function applies the linear operator to a vector.

Parameters

[out]	Hv	is the output vector.
[in]	v	is the input vector.
[in]	tol	is a tolerance for inexact linear operator application.

Implements ROL::LinearOperator< Real >.

inlinevirtual

Apply adjoint of linear operator.

This function applies the adjoint of a linear operator to a vector. Default behavior assumes operator is self-adjoint.

Parameters

[out]	Hv	is the output vector.
[in]	v	is the input vector.
[in]	tol	is a tolerance for inexact linear operator application.

inlinevirtual

Apply inverse of linear operator.

This function applies the inverse of linear operator to a vector.

Parameters

[out]	Hv	is the output vector.
[in]	v	is the input vector.
[in]	tol	is a tolerance for inexact linear operator application.

Reimplemented from ROL::LinearOperator< Real >.
