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