◆ 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.
◆ rows()
template<typename MT , bool SO>
Returns the current number of rows of the matrix.
- Returns
- The number of rows of the matrix.
◆ useAssign
template<typename MT , bool SO>
Compilation switch for the serial evaluation strategy of the strictly upper declaration expression.
The useAssign compile time constant expression represents a compilation switch for the serial evaluation strategy of the strictly upper declaration expression. In case the given dense matrix expression of type MT requires an intermediate evaluation, useAssign will be set to 1 and the strictly upper declaration 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.
