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