Detailed Description

template<typename Result, typename Left, typename Right, typename Scalar, bool LeftConsumable, bool RightConsumable>
class TiledArray::detail::ScalMult< Result, Left, Right, Scalar, LeftConsumable, RightConsumable >

Tile scale-multiplication operation.

This multiplication operation will multiply the content two tiles and apply a permutation to the result tensor. If no permutation is given or the permutation is null, then the result is not permuted.

Template Parameters

Result	The result tile type
Left	The left-hand argument type
Right	The right-hand argument type
Scalar	The scaling factor type
LeftConsumable	If true, the left-hand tile is a temporary and may be consumed
RightConsumable	If true, the right-hand tile is a temporary and may be consumed

Note

Input tiles can be consumed only if their type matches the result type.
