function varargout = mygui(varargin)% MYGUI M-file for mygui.fig% MYGUI, by itself, creates a new MYGUI or raises the existing% singleton*.% H = MYGUI returns the handle to a new MYGUI or the handle to% the existing singleton*.% MYGUI(CALLBACK,hObject,eventData,handles,.) calls the local% function named CALLBACK in MYGUI.M with the given input arguments.% MYGUI(Property,Value,.) creates a new MYGUI or raises the% existing singleton*. Starting from the left, property value pairs are% applied to the GUI before mygui_OpeningFcn gets called. An% unrecognized property name or invalid value makes property application% stop.
