template<typename MT1, typename MT2>
class blaze::SMatTSMatSubExpr< MT1, MT2 >
Expression object for sparse matrix-transpose sparse matrix subtractions.
The SMatTSMatSubExpr class represents the compile time expression for subtractions between a row-major sparse matrix and a column-major sparse matrix.
◆ anonymous enum
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.
◆ SMatTSMatSubExpr()
template<typename MT1 , typename MT2 >
Constructor for the SMatTSMatSubExpr class.
- Parameters
-
lhs | The left-hand side sparse matrix operand of the subtraction expression. |
rhs | The right-hand side sparse matrix operand of the subtraction expression. |
◆ at()
template<typename MT1 , typename MT2 >
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 >
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.
◆ columns()
template<typename MT1 , typename MT2 >
Returns the current number of columns of the matrix.
- Returns
- The number of columns of the matrix.
◆ isAliased()
template<typename MT1 , typename MT2 >
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.
◆ leftOperand()
template<typename MT1 , typename MT2 >

◆ operator()()
template<typename MT1 , typename MT2 >
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 . |
- Returns
- The resulting value.
◆ operator~() [1/2]
Conversion operator for non-constant matrices.
