TiledArray::detail::Subt< Result, Left, Right, LeftConsumable, RightConsumable > Class Template Reference

Documentation

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

Tile subtraction operation.

This subtraction operation will subtract the content two tiles, and accepts an optional permute argument.

Template Parameters

Result	The result tile type
Left	The left-hand argument base type
Right	The right-hand argument base 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.

template<typename R >

result_type TiledArray::detail::Subt< Result, Left, Right, LeftConsumable, RightConsumable >::consume_left ( left_type &  left, R &&  right  ) const

inline

Subtract right to left.

Subtract the right tile to the left. The right tile may be replaced with ZeroTensor argument, in which case the argument's element values are assumed to be 0.

Template Parameters

R	The right-hand tile argument type

Parameters

left	The left-hand tile argument
right	The right-hand tile argument

Returns

The difference of left and right.

Definition at line 188 of file subt.h.

consume_right()

template<typename L >

result_type TiledArray::detail::Subt< Result, Left, Right, LeftConsumable, RightConsumable >::consume_right ( L &&  left, right_type &  right  ) const

inline

Subtract left to right.

Subtract the left tile to the right. The left tile may be replaced with ZeroTensor argument, in which case the argument's element values are assumed to be 0.

Template Parameters

L	The left-hand tile argument type

Parameters

left	The left-hand tile argument
right	The right-hand tile argument

Returns

The difference of left and right.

Definition at line 208 of file subt.h.

operator()() [1/2]

template<typename Result , typename Left , typename Right , bool LeftConsumable, bool RightConsumable>

template<typename L , typename R >

result_type TiledArray::detail::Subt< Result, Left, Right, LeftConsumable, RightConsumable >::operator() ( L &&  left, R &&  right  ) const

inline

Subtract operator.

Compute the difference of two tiles. One of the argument tiles may be replaced with ZeroTensor argument, in which case the argument's element values are assumed to be 0.

Template Parameters

L	The left-hand tile argument type
R	The right-hand tile argument type

Parameters

left	The left-hand tile argument
right	The right-hand tile argument

Returns

The scaled difference of left and right.

operator()() [2/2]

template<typename Result , typename Left , typename Right , bool LeftConsumable, bool RightConsumable>

template<typename L , typename R , typename Perm , typename = std::enable_if_t<TiledArray::detail::is_permutation_v<Perm>>>

result_type TiledArray::detail::Subt< Result, Left, Right, LeftConsumable, RightConsumable >::operator() ( L &&  left, R &&  right, const Perm &  perm  ) const

inline

Subtract-and-permute operator.

Compute the difference of two tiles and permute the result. One of the argument tiles may be replaced with ZeroTensor argument, in which case the argument's element values are assumed to be 0.

Template Parameters

L	The left-hand tile argument type
R	The right-hand tile argument type

Parameters

left	The left-hand tile argument
right	The right-hand tile argument
perm	The permutation applied to the result tile

Returns

The permuted and scaled difference of left and right.
