Class template default_error_checker

boost::numeric::odeint::default_error_checker — The default error checker to be used with Runge-Kutta error steppers.

Synopsis

// In header: <boost/numeric/odeint/stepper/controlled_runge_kutta.hpp>
template<typename Value, typename Algebra, typename Operations>
class default_error_checker {
public:
  // types
  typedef Value      value_type;
  typedef Algebra    algebra_type;
  typedef Operations operations_type;
  // construct/copy/destruct
  default_error_checker(value_type = static_cast< value_type >(1.0e-6),
                        value_type = static_cast< value_type >(1.0e-6),
                        value_type = static_cast< value_type >(1),
                        value_type = static_cast< value_type >(1));
  // public member functions
  template<typename State, typename Deriv, typename Err, typename Time>
    value_type error(const State &, const Deriv &, Err &, Time) const;
  template<typename State, typename Deriv, typename Err, typename Time>
    value_type error(algebra_type &, const State &, const Deriv &, Err &,
                     Time) const;
};

Description

Этот класс обеспечивает механизм по умолчанию для сравнения оценок ошибок, сообщаемых шагами ошибки Runge-Kutta, с установленными пользователем границами ошибок. Используется с помощью программы control_runge_kutta steppers.
