Detailed Description

template<class MI, class IMS, class SPB, std::size_t C>
class Dune::Functions::PowerPreBasis< MI, IMS, SPB, C >

A pre-basis for power bases.

This pre-basis represents a power of a given pre-basis. Its node type is a PowerBasisNodes for the given subnode.

Template Parameters

MI	Type to be used for multi-indices
IMS	An IndexMergingStrategy used to merge the global indices of the child factories
SPB	The child pre-basis
C	The exponent of the power node
