Umatrix Methods

Operation Details public Umatrix(): Notes: Constructor public Umatrix(    KohonenNetwork SOM,    Point DrawingPosition,    Size DrawingSize): Notes: Constructor public Umatrix(    KohonenNetwork SOM): Notes: Constructor public Umatrix(    KohonenNetwork SOM,    int top,    int bottom,    int left,    int right): Notes: Constructor public BottomColor():Color <<property>> Notes: Color for the nearest neurons public TopColor():Color <<property>> Notes: Color for the most distant neurons public DrawingPosition():Point <<property>> Notes: Position, where U-matrix will be painted public DrawingSize():Size <<property>> Notes: Size of rectangle, where will U-matrix painted public SOM():KohonenNetwork <<property>> Notes: Network for drawing public IsEmpty():bool <<property>> Notes: if SOM == null then isEmpty return true, else false. public DrawText():bool <<property>> Notes: If true, then will be painted RowName of rows from table next to neurons public DrawClusters():bool <<property>> Notes: if true, then will be painted border between neurons from diferent clusters. public DrawClusterID():bool <<property>> Notes: if true, then will be painted cluster ID of neuron. public DrawingRectangle(    int left,    int right,    int top,    int bottom):void Notes: set of rectangle for drawing private CalculateHexagonPosition():void Notes: Calculate position of hexagons private ClearTextField():void Notes: Remove Row Name from neurons. private SetNeurons():void Notes: Set neurons private SetDistance():void Notes: Set distance between neurons private SetClustersSeparators():void Notes: Set cluster separators private SetColors():void Notes: Set colors for all hexagons in U-matrix. Colors are normalized for interval (0, mostDistancedNeuron) private SetDescriptiveText():void Notes: Set descriptive text (Row name). Get all rows from table, and for every row find nearest neuron. For this neuron add row name to Hexagon.Text properties. Set descriptive text is very demanding operation. Complexity of this operation is O(M*N), whre M is count of neurons in networks and N is count of entries in table. public getPoint(    int index,    int width,    int height):Point Notes: Convert point in one dimensional array to two dimensional posision in array with "width" x "height" size @returns private FindWinner(    double[] vector):int Notes: Find the nearest neuron for given vector @returns index of winner neurons public Distance(    double[] vector,    double[] weights):double Notes: Calculate Euclidian distance between tvo vectors @returns private NormalizedColor(    Color bottomColor,    Color topColor,    double dist,    double max):Color Notes: Normalized color. BottomColor is maped to 0 and TopColor is maped to max. Color between them are liner maped to interval (0, max). @returns color for dist parameter private FindMaxDistance():double Notes: Run through array of hexagon, and find the maximum distance between neurons @returns maximum distance private GetHexagonVertex(    PointF position,    float a,    float b):PointF Notes: Return a position of hexagon vertex @returns array of hexagon vertex public Draw(    Graphics grfx):void Notes: Draw U-matrix public Draw(    Graphics grfx,    int top,    int left,    int bottom,    int right):void Notes: Draw U-matrix
