template<typename MT1, typename MT2>
class blaze::DMatTDMatSchurExpr< MT1, MT2 >
Expression object for dense matrix-transpose dense matrix Schur product.
The DMatTDMatSchurExpr class represents the compile time expression for Schur product between a row-major dense matrix and a column-major dense matrix.
◆ DMatTDMatSchurExpr()
template<typename MT1 , typename MT2 >
Constructor for the DMatTDMatSchurExpr class.

j | Access index for the column. The index has to be in the range . |
- Returns
- The resulting value.
- Exceptions

◆ operator*() [1/2]
|
constexprnoexceptinherited |
CRTP-based conversion operation for constant matrices.
- Returns
- Constant reference of the actual type of the matrix.
This operator performs the CRTP-based type-safe downcast to the actual type MT of the matrix. It will return a constant reference to the actual type MT.
◆ operator*() [2/2]
|
constexprnoexceptinherited |
CRTP-based conversion operation for non-constant matrices.
- Returns
- Mutable reference of the actual type of the matrix.
This operator performs the CRTP-based type-safe downcast to the actual type MT of the matrix. It will return a mutable reference to the actual type MT.
◆ operator~() [1/2]
|
constexprnoexceptinherited |
CRTP-based conversion operation for constant matrices.
- Parameters
-
matrix | The matrix to be downcast. |
- Returns
- Constant reference of the actual type of the matrix.
This operator performs the CRTP-based type-safe downcast to the actual type MT of the matrix. It will return a constant reference to the actual type MT.
◆ operator~() [2/2]
|
constexprnoexceptinherited |
CRTP-based conversion operation for non-constant matrices.
- Parameters
-
matrix | The matrix to be downcast. |
- Returns
- Mutable reference of the actual type of the matrix.
This operator performs the CRTP-based type-safe downcast to the actual type MT of the matrix. It will return a mutable reference to the actual type MT.
◆ rightOperand()
template<typename MT1 , typename MT2 >
Returns the right-hand side transpose dense matrix operand.
- Returns
- The right-hand side transpose dense matrix operand.
◆ rows()
template<typename MT1 , typename MT2 >
Returns the current number of rows of the matrix.
- Returns
- The number of rows of the matrix.
◆ returnExpr
template<typename MT1 , typename MT2 >
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.
◆ useAssign
template<typename MT1 , typename MT2 >
Initial value:=
( RequiresEvaluation_v<MT1> || RequiresEvaluation_v<MT2> || !
returnExpr )
static constexpr bool returnExpr
Compilation switch for the selection of the subscript operator return type.
Definition: DMatTDMatSchurExpr.h:123
Compilation switch for the serial evaluation strategy of the Schur product expression.
The useAssign compile time constant expression represents a compilation switch for the serial evaluation strategy of the Schur product 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 Schur product 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.
