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