template<typename VT, typename MT>
class blaze::TSVecSMatMultExpr< VT, MT >
Expression object for sparse vector-sparse matrix multiplications.
The TSVecSMatMultExpr class represents the compile time expression for multiplications between transpose sparse vectors and row-major sparse matrices.
◆ TSVecSMatMultExpr()
template<typename VT , typename MT >
Constructor for the TSVecSMatMultExpr class.
- Parameters
-
vec | The left-hand side sparse vector operand of the multiplication expression. |
mat | The right-hand side sparse matrix operand of the multiplication expression. |
◆ 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.
◆ leftOperand()
template<typename VT , typename MT >
Returns the left-hand side sparse vector operand.
- Returns
- The left-hand side sparse vector operand.
◆ nonZeros()
template<typename VT , typename MT >
Returns an estimation for the number of non-zero elements in the sparse vector.

- The estimate for the number of non-zero elements in the sparse vector.
◆ 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.

|
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

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.
