template<typename MT, bool SO>
class blaze::DMatTransExpr< MT, SO >
Expression object for dense matrix transpositions.
The DMatTransExpr class represents the compile time expression for transpositions of dense matrices.
◆ anonymous enum
template<typename MT, bool SO>
Compilation switch for the serial evaluation strategy of the transposition expression.
The useAssign compile time constant expression represents a compilation switch for the serial evaluation strategy of the transposition expression. In case the given dense matrix expression of type MT requires an intermediate evaluation, useAssign will be set to 1 and the transposition 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.
