template<typename VT1, typename VT2>
class blaze::SVecSVecOuterExpr< VT1, VT2 >
Expression object for sparse vector-sparse vector outer products.
The SVecSVecOuterExpr class represents the compile time expression for sparse vector-sparse vector outer products.
◆ anonymous enum
template<typename VT1 , typename VT2 >
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 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.
◆ SVecSVecOuterExpr()
template<typename VT1 , typename VT2 >
Constructor for the SVecSVecOuterExpr class.
- Parameters
-
lhs | The left-hand side sparse vector operand of the multiplication expression. |
rhs | The right-hand side sparse vector operand of the multiplication expression. |
◆ at()
template<typename VT1 , typename VT2 >
