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