根据matlab的肌电信号管理组织程序

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