template<class Real, class Element>
void ROL::DualScaledStdVector< Real, Element >::set ( const Vector< Real > &  x)
inlinevirtual

Set \(y \leftarrow x\) where \(y = \mathtt{*this}\).

Parameters
[in]xis a vector.

On return \(\mathtt{*this} = x\). Uses zero and plus methods for the computation. Please overload if a more efficient implementation is needed.


Reimplemented from ROL::Vector< Real >.

template<class Real, class Element>
void ROL::DualScaledStdVector< Real, Element >::plus ( const Vector< Real > &  x)
inlinevirtual

Compute \(y \leftarrow y + x\), where \(y = \mathtt{*this}\).

Parameters
[in]xis the vector to be added to \(\mathtt{*this}\).

On return \(\mathtt{*this} = \mathtt{*this} + x\).

)
inlinevirtual

Compute \(y \leftarrow \alpha x + y\) where \(y = \mathtt{*this}\).

Parameters
[in]alphais the scaling of x.
[in]xis a vector.

On return \(\mathtt{*this} = \mathtt{*this} + \alpha x \). Uses clone, set, scale and plus for the computation. Please overload if a more efficient implementation is needed.

const ROL::Vector<Real>& ROL::DualScaledStdVector< Real, Element >::dual ( void  ) const
inlinevirtual

Return dual representation of \(\mathtt{*this}\), for example, the result of applying a Riesz map, or change of basis, or change of memory layout.

Returns
A const reference to dual representation.

By default, returns the current object. Please overload if you need a dual representation.

inlinevirtual

Return i-th basis vector.

Parameters
[in]iis the index of the basis function.
Returns
A reference-counted pointer to the basis vector with index i.

Overloading the basis is only required if the default gradient implementation is used, which computes a finite-difference approximation.
