seril2.m

matlab通过串口采集心电的GUI程序

%项目：本程序用于心电图机的上位机程序，用于心电图的显示
%版本：version 4
%修改：加入了50Hz的陷波器（version 3），成功生成exe文件，通过测试
%修改日期：2008.3.29  12：27    陈刚
function varargout = seril2(varargin)
% SERIL2 M-file for seril2.fig
%      SERIL2, by itself, creates a new SERIL2 or raises the existing
%      singleton*.
%
%      H = SERIL2 returns the handle to a new SERIL2 or the handle to
%      the existing singleton*.
%
%      SERIL2('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in SERIL2.M with the given input arguments.
%
%      SERIL2('Property','Value',...) creates a new SERIL2 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before seril2_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to seril2_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
