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)".
%
% See also: GUIDE, GUIDATA, GUIHANDLES
% Edit the above text to modify the response to help GUI_ECG
