function varargout = Cnvex_Hull(varargin)
% CNVEX_HULL M-file for Cnvex_Hull.fig
%      CNVEX_HULL, by itself, creates a new CNVEX_HULL or raises the existing
%      singleton*.
%
%      H = CNVEX_HULL returns the handle to a new CNVEX_HULL or the handle to
%      the existing singleton*.
%
%      CNVEX_HULL('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in CNVEX_HULL.M with the given input arguments.
%
%      CNVEX_HULL('Property','Value',...) creates a new CNVEX_HULL or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before Cnvex_Hull_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to Cnvex_Hull_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
