三、部分源代码

function varargout = GUI_ECG(varargin)
%GUI_ECG M-file for GUI_ECG.fig
%      GUI_ECG, by itself, creates a new GUI_ECG or raises the existing
%      singleton*.
%
%      H = GUI_ECG returns the handle to a new GUI_ECG or the handle to
%      the existing singleton*.
%
%      GUI_ECG('Property','Value',...) creates a new GUI_ECG using the
%      given property value pairs. Unrecognized properties are passed via
%      varargin to GUI_ECG_OpeningFcn.  This calling syntax produces a
%      warning when there is an existing singleton*.
%
%      GUI_ECG('CALLBACK') and GUI_ECG('CALLBACK',hObject,...) call the
%      local function named CALLBACK in GUI_ECG.M with the given input
%      arguments.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
