|
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 sparse matrix operand.

- The right-hand side sparse 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.
