Detailed Description

template<typename TDomain, typename TAlgebra>
class ug::StdInjection< TDomain, TAlgebra >

The Projection operator transfers is used to transfer vectors between two grid levels. It implements a purely algebraic interface, just mapping between two algebraic vectors, but given the approximation space this is indeed a mapping between two grid functions.

Template Parameters

TDomain	the domain
TAlgebra	the algebra
