template<typename MT1, typename MT2, bool SO>
class blaze::SMatDMatSubExpr< MT1, MT2, SO >
Expression object for sparse matrix-dense matrix subtractions.
The SMatDMatSubExpr class represents the compile time expression for subtractions between a sparse matrix and a dense matrix with identical storage order.
◆ anonymous enum
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.
◆ SMatDMatSubExpr()
template<typename MT1 , typename MT2 , bool SO>
Constructor for the SMatDMatSubExpr class.
- Parameters
-
lhs | The left-hand side sparse matrix operand of the addition expression. |
rhs | The right-hand side dense matrix 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

std::out_of_range | Invalid matrix access index. |
◆ canAlias()
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. |

◆ isAliased()
template<typename MT1 , typename MT2 , bool SO>
template<typename T >
Returns whether the expression is aliased with the given address alias.
