virtual Real ROL::RieszDualVector< Real >::dot ( const V & x ) const

inlinevirtual

Compute \( \langle y,x \rangle \) where \(y = \mathtt{*this}\).

Parameters

[in] x is the vector that forms the dot product with \(\mathtt{*this}\).

Returns: The number equal to \(\langle \mathtt{*this}, x \rangle\).

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.

void ROL::RieszDualVector< Real >::setScalar ( const Real C )

inlinevirtual

Set \(y \leftarrow C\) where \(C\in\mathbb{R}\).

Parameters

[in] C is a scalar.

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

inlinevirtual

Set vector to be uniform random between [l,u].

Parameters

[in]	l	is a the lower bound.
[in]	u	is a the upper bound.

On return the components of \(\mathtt{*this}\) are uniform random numbers on the interval \([l,u]\). The default implementation uses applyUnary methods for the computation. Please overload if a more efficient implementation is needed.
