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