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