template<typename VT1, typename VT2, bool TF>
class blaze::DVecDVecDivExpr< VT1, VT2, TF >
Expression object for dense vector-dense vector divisions.
The DVecDVecDivExpr class represents the compile time expression for componentwise divisions between dense vectors.
◆ DVecDVecDivExpr()
template<typename VT1 , typename VT2 , bool TF>
Constructor for the DVecDVecDivExpr class.
- Parameters
-
lhs | The left-hand side operand of the division expression. |
rhs | The right-hand side operand of the division expression. |
◆ at()
template<typename VT1 , typename VT2 , bool TF>
Checked access to the vector elements.
- Parameters
-
index | Access index. The index has to be in the range . |
- Returns
- The resulting value.
- Exceptions
-
std::out_of_range | Invalid vector access index. |
◆ begin()
template<typename VT1 , typename VT2 , bool TF>
Returns an iterator to the first non-zero element of the dense vector.
- Returns
- Iterator to the first non-zero element of the dense vector.
◆ canAlias()
template<typename VT1 , typename VT2 , bool TF>
template<typename T >
Returns whether the expression can alias with the given address alias.
- Parameters
-
alias | The alias to be checked. |
- Returns
- true in case the expression can alias, false otherwise.
◆ canSMPAssign()
template<typename VT1 , typename VT2 , bool TF>
Returns whether the expression can be used in SMP assignments.
- Returns
- true in case the expression can be used in SMP assignments, false if not.
◆ end()
template<typename VT1 , typename VT2 , bool TF>
Returns an iterator just past the last non-zero element of the dense vector.
- Returns
- Iterator just past the last non-zero element of the dense vector.
◆ isAliased()
template<typename VT1 , typename VT2 , bool TF>
template<typename T >
Returns whether the expression is aliased with the given address alias.
- Parameters
-
alias | The alias to be checked. |
- Returns
- true in case an alias effect is detected, false otherwise.
◆ isAligned()
template<typename VT1 , typename VT2 , bool TF>
Returns whether the operands of the expression are properly aligned in memory.
- Returns
- true in case the operands are aligned, false if not.
◆ leftOperand()
template<typename VT1 , typename VT2 , bool TF>
Returns the left-hand side dense vector operand.
- Returns
- The left-hand side dense vector operand.
◆ load()
template<typename VT1 , typename VT2 , bool TF>
Access to the SIMD elements of the vector.
- Parameters
-
index | Access index. The index has to be in the range . |
- Returns
- Reference to the accessed values.
◆ operator[]()
template<typename VT1 , typename VT2 , bool TF>
Subscript operator for the direct access to the vector elements.
- Parameters
-
index | Access index. The index has to be in the range . |
- Returns
- The resulting value.
◆ operator~() [1/2]
template<typename VT, bool TF>
Conversion operator for non-constant vectors.
- Returns
- Reference of the actual type of the vector.
◆ operator~() [2/2]
template<typename VT, bool TF>
Conversion operator for constant vectors.
- Returns
- Const reference of the actual type of the vector.
◆ rightOperand()
template<typename VT1 , typename VT2 , bool TF>
Returns the right-hand side dense vector operand.
- Returns
- The right-hand side dense vector operand.
◆ size()
template<typename VT1 , typename VT2 , bool TF>
Returns the current size/dimension of the vector.
- Returns
- The size of the vector.
◆ returnExpr
template<typename VT1 , typename VT2 , bool TF>
Compilation switch for the selection of the subscript operator return type.
The returnExpr compile time constant expression is a compilation switch for the selection of the ReturnType. If either vector operand returns a temporary vector or matrix, returnExpr will be set to 0 and the subscript operator will return it's result by value. Otherwise returnExpr will be set to 1 and the subscript operator may return it's result as an expression.
◆ simdEnabled
template<typename VT1 , typename VT2 , bool TF>
Initial value:=
( VT1::simdEnabled && VT2::simdEnabled && HasSIMDDiv_v<ET1,ET2> )
Compilation switch for the expression template evaluation strategy.
◆ useAssign
template<typename VT1 , typename VT2 , bool TF>
Initial value:=
( RequiresEvaluation_v<VT1> || RequiresEvaluation_v<VT2> || !
returnExpr )
Compilation switch for the serial evaluation strategy of the division expression.
The useAssign compile time constant expression represents a compilation switch for the serial evaluation strategy of the division expression. In case either of the two dense vector operands requires an intermediate evaluation or the subscript operator can only return by value, useAssign will be set to 1 and the division expression will be evaluated via the assign function family. Otherwise useAssign will be set to 0 and the expression will be evaluated via the subscript operator.
