class blaze::DVecDVecSubExpr< VT1, VT2, TF >
Expression object for dense vector-dense vector subtractions.
The DVecDVecSubExpr class represents the compile time expression for subtractions between dense vectors.
template<typename VT1, typename VT2, bool TF>
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 VT1, typename VT2, bool TF>
Compilation switch for the evaluation strategy of the subtraction expression.
The useAssign compile time constant expression represents a compilation switch for the evaluation strategy of the subtraction expression. In case either of the two dense vector operands requires an intermediate evaluation or the subscript operator can only return by value, useAssign will be set to true and the subtraction 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.
