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