1、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,eventd

2、ata,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

3、% 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. choose gui allows only one% instance to run (singleton).% see also: guide, guidata, guihandles % edit the above text to m
