class blaze::DMatDMatAddExpr< MT1, MT2, SO >
Expression object for dense matrix-dense matrix additions.
The DMatDMatAddExpr class represents the compile time expression for additions between dense matrices with identical storage order.
◆ DMatDMatAddExpr()
template<typename MT1 , typename MT2 , bool SO>

rhs | The right-hand side operand of the addition expression. |
◆ at()
template<typename MT1 , typename MT2 , bool SO>
Checked access to the matrix elements.
- Parameters
-
i | Access index for the row. The index has to be in the range . |
j | Access index for the column. The index has to be in the range . |
- Returns
- The resulting value.
- Exceptions

template<typename MT1 , typename MT2 , bool SO>
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 MT1 , typename MT2 , bool SO>

◆ end()
template<typename MT1 , typename MT2 , bool SO>
Returns an iterator just past the last non-zero element of row i.
- Parameters
-
- Returns
- Iterator just past the last non-zero element of row i.
◆ isAliased()
template<typename MT1 , typename MT2 , bool SO>
template<typename T >
Returns whether the expression is aliased with the given address alias.

i | Access index for the row. The index has to be in the range . |
j | Access index for the column. The index has to be in the range . |
- Returns
- Reference to the accessed values.
◆ operator()()

i | Access index for the row. The index has to be in the range . |
j | Access index for the column. The index has to be in the range . |
- Returns
- The resulting value.
◆ operator~() [1/2]
template<typename MT, bool SO>
Conversion operator for non-constant matrices.
- Returns
- Reference of the actual type of the matrix.
◆ operator~() [2/2]
template<typename MT, bool SO>

- Returns
- The number of rows of the matrix.
◆ returnExpr
template<typename MT1 , typename MT2 , bool SO>
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 matrix operand returns a temporary vector or matrix, returnExpr will be set to false and the subscript operator will return it's result by value. Otherwise returnExpr will be set to true and the subscript operator may return it's result as an expression.
◆ simdEnabled
template<typename MT1 , typename MT2 , bool SO>
Initial value:=
( MT1::simdEnabled && MT2::simdEnabled && HasSIMDAdd_v<ET1,ET2> )
Compilation switch for the expression template evaluation strategy.
◆ useAssign
template<typename MT1 , typename MT2 , bool SO>
Initial value:=
( RequiresEvaluation_v<MT1> || RequiresEvaluation_v<MT2> || !
returnExpr )
Compilation switch for the serial evaluation strategy of the addition expression.
The useAssign compile time constant expression represents a compilation switch for the serial evaluation strategy of the addition expression. In case either of the two dense matrix operands requires an intermediate evaluation or the subscript operator can only return by value, useAssign will be set to 1 and the addition expression will be evaluated via the assign function family. Otherwise useAssign will be set to 0 and the expression will be evaluated via the function call operator.
