function varargout = plot(t,varargin) %PLOT Plot RWVTREE object. % PLOT(T) plots the RWVTREE object T. % FIG = PLOT(T) returns the handle of the figure, which % contains the tree T. % PLOT(T,FIG) plots the tree T in the figure FIG, which % already contains a tree. % % PLOT is a graphical tree-management utility. The figure % that contains the tree is a GUI tool. It lets you change % the Node Label to Depth_Position or Index, and Node Action % to Split-Merge or Visualize. % The default values are Depth_Position and Visualize. % % You can click the nodes to execute the current Node Action. % % After some split or merge actions you can get the new tree % using the handle of the figure, which contains it. % You must use the following special syntax: % NEWT = PLOT(T,'read',FIG). % In fact, the first argument is dummy. Then the most general % syntax for this purpose is: % NEWT = PLOT(DUMMY,'READ',FIG); % where DUMMY is any object parented by an NTREE object. % % DUMMY can be any object constructor name, which returns % an object parented by an NTREE object. For example: % NEWT = PLOT(ntree,'read',FIG); % NEWT = PLOT(dtree,'read',FIG); % M. Misiti, Y. Misiti, G. Oppenheim, J.M.
