template<typename VT1, typename VT2>
class blaze::DVecDVecOuterExpr< VT1, VT2 >
Expression object for outer products between two dense vectors.
The DVecDVecOuterExpr class represents the compile time expression for outer products between dense vectors.
◆ 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.
◆ anonymous enum
template<typename VT1 , typename VT2 >
Compilation switch for the serial evaluation strategy of the outer product expression.
The useAssign compile time constant expression represents a compilation switch for the serial evaluation strategy of the outer product expression. In case either of the two dense vector operands requires an evaluation, useAssign will be set to true and the outer product expression will be evaluated via the assign function family. Otherwise useAssign will be set to false and the expression will be evaluated via the function call operator.
