Public Member Functions
	DS ()
	default constructors
virtual int	max_length ()
	Returns maximum number of provided data, by default it is set to maximum allowed length, shorter DS should overload this method! See, MemDS.max_length().
virtual void	getdata (vec &dt_out) const
	Returns full vector of observed data=[output, input].
virtual void	getdata (vec &dt_out, const ivec &indices)
	Returns data records at indices. Default is inefficent.
virtual void	write (const vec &ut) NOT_IMPLEMENTED_VOID
	Accepts action variable and schedule it for application.
virtual void	write (const vec &ut, const ivec &indices) NOT_IMPLEMENTED_VOID
	Accepts action variables at specific indices.
virtual void	step ()=0
	Moves from to , i.e. perfroms the actions and reads response of the system.
virtual void	log_register (logger &L, const string &prefix)
	Register DS for logging into logger L.
virtual void	log_write () const
	Register DS for logging into logger L.

Detailed Description

The class abstracts operations of:

• data aquisition,
• data-preprocessing, such as scaling of data,
• data resampling from the task of estimation and control. Moreover, for controlled systems, it is able to receive the desired control action and perform it in the next step. (Or as soon as possible).

• input, , which are described via RVs in attribute urv
• observations , which are described in drv In simulators, dt may contain "hidden" variables as well.

Member Function Documentation

    drv  = RV({"names",...},[..sizes..]);            % decription of observed data using bdm::RV::from_setting
    urv  = RV({"names",...},[..sizes..]);            % decription of input data using bdm::RV::from_setting
    log_level = 'logdt,logut';               % when set, both the simulated data and the inputs are stored to the logger
                                             % By default both are on. It makes sense to switch them off e.g. for MemDS where the data are already stored.
