Base template for the DeclDiagTrait class.
The DeclDiagTrait class template offers the possibility to select the resulting data type of a generic decldiag() operation on the given type MT. DeclDiagTrait defines the nested type Type, which represents the resulting data type of the decldiag() operation. In case the given data type is not a dense or sparse matrix type, the resulting data type Type is set to INVALID_TYPE. Note that const and volatile qualifiers and reference modifiers are generally ignored.
Per default, the DeclDiagTrait template only supports the following matrix types:
It is possible to specialize the DeclDiagTrait template for additional user-defined matrix types. The following example shows the according specialization for the SymmetricMatrix class template:
The following example demonstrates the use of the DeclDiagTrait template, where depending on the given matrix type the resulting type is selected:
