我刚开始学gui编程，第一个程序编译成.exe后，运行的时候先出现错误提示如下：
然后就是程序界面一闪即逝。
请问这时什么引起的？
怎么修改？
谢谢！
源程序如下：
源程序如下：
function varargout = signal(varargin)
% SIGNAL M-file for signal.fig
% SIGNAL, by itself, creates a new SIGNAL or raises the existing
% singleton*.
%
% H = SIGNAL returns the handle to a new SIGNAL or the handle to
% the existing singleton*.
%
% SIGNAL('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in SIGNAL.M with the given input arguments.
%
% SIGNAL('Property','Value',...) creates a new SIGNAL or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before signal_OpeningFunction gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to signal_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

% See also: GUIDE, GUIDATA, GUIHANDLES
