Detailed Description

template<class ScalarType>
class MyOperator< ScalarType >

Simple example of a user's defined Belos::Operator class.

This is a simple, single processor example of user's defined Belos::Operator-derived class. The class is templated with ScalarType; possible choices are, for example, "float", "double", or "std::complex<double>".

This file can be easily extended to tackle more interesting cases.
