Public Member Functions
void	getdata (vec &dt0)
	Returns full vector of observed data=[output, input].
void	getdata (vec &dt0, const ivec &indices)
	Returns data records at indeces.
	stateDS (const shared_ptr< mpdf > &IM0, const shared_ptr< mpdf > &OM0, int usize)
	convenience constructor
virtual void	step ()
	Moves from to , i.e. perfroms the actions and reads response of the system.
virtual void	log_add (logger &L)

virtual void	logit (logger &L)
	Register DS for logging into logger L.
void	from_setting (const Setting &set)
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	write (const vec &ut)
	Accepts action variable and schedule it for application.
virtual void	write (const vec &ut, const ivec &indeces)
	Accepts action variables at specific indeces.

UI for stateDS

The DS is constructed from a structure with fields:

                system = {
                        type = "stateDS";
                        //Internal model
                        IM = { type = "mpdf"; //<-- valid offspring! e.g. "mlnorm"
                                rv = { //description of x_t
                                        names=["name1",...];
                                        sizes=[2,1]; // optional default=[1,1...];
                                        times=[0,0]; // optional default=[0,0...];
                                        }
                                rvu= { //description of  u_t
                                        //optional default=empty
                                        }

                                // remaining fields depending on the chosen type
                                };
                        //Observation model
                        OM = { type = "mpdf-offspring";
                                rv = {}; //description of d_t
                                rvu = {type="internal", path="system.IM.rvu"}; //description of u_t

                                //remaining fields
                        }
                };

Reimplemented from bdm::root.
