template<typename VT, typename MT>
class blaze::TDVecTSMatMultExpr< VT, MT >
Expression object for transpose dense vector-transpose sparse matrix multiplications.
The TDVecTSMatMultExpr class represents the compile time expression for multiplications between transpose dense vectors and column-major sparse matrices.
◆ at()
template<typename VT , typename MT >
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. |
◆ canAlias()
template<typename VT , typename MT >
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 VT , typename MT >
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.
◆ isAliased()
template<typename VT , typename MT >
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 VT , typename MT >
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 VT , typename MT >
Returns the left-hand side dense vector operand.
- Returns
- The left-hand side dense vector operand.
◆ operator*() [1/2]
|
constexprnoexceptinherited |
CRTP-based conversion operation for constant vectors.
- Returns
- Const reference of the actual type of the vector.
This operator performs the CRTP-based type-safe downcast to the actual type VT of the vector. It will return a constant reference to the actual type VT.
◆ operator*() [2/2]
|
constexprnoexceptinherited |
CRTP-based conversion operation for non-constant vectors.
- Returns
- Mutable reference of the actual type of the vector.
This operator performs the CRTP-based type-safe downcast to the actual type VT of the vector. It will return a mutable reference to the actual type VT.
◆ operator[]()
template<typename VT , typename MT >
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]
|
constexprnoexceptinherited |
CRTP-based conversion operation for constant vectors.
- Returns
- Constant reference of the actual type of the vector.
This operator performs the CRTP-based type-safe downcast to the actual type VT of the vector. It will return a constant reference to the actual type VT.
◆ operator~() [2/2]
|
constexprnoexceptinherited |
CRTP-based conversion operation for non-constant vectors.
- Returns
- Mutable reference of the actual type of the vector.
This operator performs the CRTP-based type-safe downcast to the actual type VT of the vector. It will return a mutable reference to the actual type VT.
◆ rightOperand()
template<typename VT , typename MT >
Returns the right-hand side transpose sparse matrix operand.
- Returns
- The right-hand side transpose sparse matrix operand.
◆ size()
template<typename VT , typename MT >
Returns the current size/dimension of the vector.
- Returns
- The size of the vector.
◆ smpAssignable
template<typename VT , typename MT >
Initial value:=
static constexpr bool evaluateMatrix
Compilation switch for the composite type of the right-hand side sparse matrix expression.
Definition: TDVecTSMatMultExpr.h:113
static constexpr bool evaluateVector
Compilation switch for the composite type of the left-hand side dense vector expression.
Definition: TDVecTSMatMultExpr.h:108
Compilation switch for the expression template assignment strategy.
◆ useAssign
template<typename VT , typename MT >
Compilation switch for the evaluation strategy of the multiplication expression.
The useAssign compile time constant expression represents a compilation switch for the evaluation strategy of the multiplication expression. In case either the vector or the matrix operand requires an intermediate evaluation or the dense vector expression is a compound expression, useAssign will be set to true and the multiplication expression will be evaluated via the assign function family. Otherwise useAssign will be set to false and the expression will be evaluated via the subscript operator.
