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