Detailed Description

template<typename VT1, typename VT2, bool TF>
class blaze::DVecSVecCrossExpr< VT1, VT2, TF >

Expression object for dense vector-sparse vector cross products.

The DVecSVecCrossExpr class represents the compile time expression for cross products between a dense vector and a sparse vector.

Member Enumeration Documentation

template<typename VT1, typename VT2, bool TF>
anonymous enum : bool
private

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.
