◆ useAssign
template<typename MT1 , typename MT2 , typename OP , bool SO>
Compilation switch for the serial evaluation strategy of the map expression.
The useAssign compile time constant expression represents a compilation switch for the serial evaluation strategy of the map expression. In case either of the two dense matrix operands requires an intermediate evaluation, useAssign will be set to 1 and the addition expression will be evaluated via the assign function family. Otherwise useAssign will be set to 0 and the expression will be evaluated via the subscript operator.
