class blaze::SVecDVecMultExpr< typename, typename, bool >
Expression object for sparse vector-dense vector multiplications.
The SVecDVecMultExpr class represents the compile time expression for componentwise multiplications between a sparse vector and a dense vector.
template<typename , typename , bool >
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.
template<typename , typename , bool >
Compilation switch for the evaluation strategy of the multiplication expression.
The useAssign compile time constant expression represents a compilation switch for the evaluation strategy of the multiplication expression. In case either the sparse or the dense vector operand requires an intermediate evaluation, useAssign will be set to true and the multiplication expression will be evaluated via the assign function family. Otherwise useAssign will be set to false and the expression will be evaluated via the subscript operator.
