EpsSelector: Selects as many points from the data that any trajectory point lies within an epsilon radius of a training point. More...
EpsSelector: Selects as many points from the data that any trajectory point lies within an epsilon radius of a training point.
This selection strategy is applied in the TPWLApprox-Setting, but may also be used elsewhere.
This class is part of the framework

| Public Member Functions inherited from ICloneable | |
| virtual function copy = | clone (target) |
| The interface method with returns a copy of the current class instance. More... | |
Public Attributes | |
| EpsRad = 5 | |
| The distance within there has to be an expansion point for each x. Gets multiplied by \(\sqrt{d}\), where \(d\) denotes the spatial dimension of the snapshots (projection training data) More... | |
| SubspaceProject = true | |
| Public Attributes inherited from data.selection.ASelector | |
| logical | EnsureUniqueData = true |
| Flag to enable automatic "uniqueification" if selected training data. Uniqueness is determined by the state space samples xi; if any xi is included twice or more, it is discarded along with the fxi, ti, mui data of the replicates (independent of whether they are equal, too) More... | |
| Public Attributes inherited from DPCMObject | |
| WorkspaceVariableName = "" | |
| The workspace variable name of this class. Optional. More... | |
| ID = "[]" | |
| An ID that allows to uniquely identify this DPCMObject (at least within the current MatLab session/context). More... | |
| PropertiesChanged = "[]" | |
| The Dictionary containing all the property settings as key/value pairs. More... | |
| Public Attributes inherited from handle | |
| addlistener | |
| Creates a listener for the specified event and assigns a callback function to execute when the event occurs. More... | |
| notify | |
| Broadcast a notice that a specific event is occurring on a specified handle object or array of handle objects. More... | |
| delete | |
| Handle object destructor method that is called when the object's lifecycle ends. More... | |
| disp | |
| Handle object disp method which is called by the display method. See the MATLAB disp function. More... | |
| display | |
| Handle object display method called when MATLAB software interprets an expression returning a handle object that is not terminated by a semicolon. See the MATLAB display function. More... | |
| findobj | |
| Finds objects matching the specified conditions from the input array of handle objects. More... | |
| findprop | |
| Returns a meta.property objects associated with the specified property name. More... | |
| fields | |
| Returns a cell array of string containing the names of public properties. More... | |
| fieldnames | |
| Returns a cell array of string containing the names of public properties. See the MATLAB fieldnames function. More... | |
| isvalid | |
| Returns a logical array in which elements are true if the corresponding elements in the input array are valid handles. This method is Sealed so you cannot override it in a handle subclass. More... | |

| Relational functions example. See details for more information. More... | |
| transpose | |
| Transposes the elements of the handle object array. More... | |
| permute | |
| Rearranges the dimensions of the handle object array. See the MATLAB permute function. More... | |
| reshape | |
