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)
virtual void step ()
 Moves from $ t $ to $ t+1 $, i.e. perfroms the actions and reads response of the system.

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
                        }
                };
