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