Base template for the SubmatrixTrait class.
The SubmatrixTrait class template offers the possibility to select the resulting data type when creating a submatrix of a dense or sparse matrix. SubmatrixTrait defines the nested type Type, which represents the resulting data type of the submatrix 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 SubmatrixTrait template only supports the following matrix types:
It is possible to specialize the SubmatrixTrait template for additional user-defined matrix types. The following example shows the according specialization for the DynamicMatrix class template:
The following example demonstrates the use of the SubmatrixTrait template, where depending on the given matrix type the according result type is selected:
