template<typename MT, bool SO>
class blaze::DMatAbsExpr< MT, SO >
Expression object for the dense matrix abs() function.
The DMatAbsExpr class represents the compile time expression for the calculation of the absolute value of each element of a dense matrix via the abs() function.
template<typename MT , 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 the vector 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.
template<typename MT , bool SO>
Compilation switch for the evaluation strategy of the absolute value expression.
The useAssign compile time constant expression represents a compilation switch for the evaluation strategy of the absolute value expression. In case the given dense matrix expression of type MT requires an intermediate evaluation, useAssign will be set to 1 and the absolute value 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.
template<typename MT , bool SO>
Constructor for the DMatAbsExpr class.
- Parameters
-
dm | The dense matrix operand of the absolute value expression. |
template<typename MT , 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.
template<typename MT , bool SO>
Returns the current number of columns of the matrix.
- Returns
- The number of columns of the matrix.
template<typename MT , bool SO>
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.
template<typename MT , bool SO>
Returns the dense matrix operand.
- Returns
- The dense matrix operand.
template<typename MT , bool SO>
2D-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 . |

- The resulting value.
template<typename , bool >
Conversion operator for non-constant matrices.
- Returns
- Reference of the actual type of the matrix.
template<typename , bool >
Conversion operator for constant matrices.
- Returns
- Constant reference of the actual type of the matrix.
template<typename MT , bool SO>
Returns the current number of rows of the matrix.
- Returns
- The number of rows of the matrix.
