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 GUIDEs Tools menu.
