Base template for the DeclUppTrait class.
The DeclUppTrait class template offers the possibility to select the resulting data type of a generic declupp() operation on the given type MT. In case the given type MT is a dense or sparse matrix type, DeclUppTrait defines the nested type Type, which represents the resulting data type of the declupp() operation. Otherwise there is no nested type Type. Note that const and volatile qualifiers and reference modifiers are generally ignored.
Per default, DeclUppTrait supports all matrix types of the Blaze library (including views and adaptors). For all other data types it is possible to specialize the DeclUppTrait template. The following example shows the according specialization for the SymmetricMatrix class template:
The following example demonstrates the use of the DeclUppTrait template, where depending on the given matrix type the resulting type is selected:
