Detailed Description

template<class Pos1, class Pos2, class ContractDims>
struct Dune::ACFem::EinsumOperation< Pos1, Pos2, ContractDims >

Einstein summation, i.e.

contraction of tensors over given index positions.

Parameters

Pos1	Index positions in first tensor.
Pos2	Index positions in second tensor.
ContractDims	Shared dimensions of the index positions specified in Pos1 and Pos2.

Requirements: size<Pos1>() == size<Pos2>() == size<ContractDims>().
