下面这个是我用guide新建的,但我只是把模样做出来,并没有把任何功能实现
function varargout = temp(varargin)
% TEMP M-file for temp.fig
%      TEMP, by itself, creates a new TEMP or raises the existing
%      singleton*.
%
%      H = TEMP returns the handle to a new TEMP or the handle to
%      the existing singleton*.
%
%      TEMP('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in TEMP.M with the given input arguments.
%
%      TEMP('Property','Value',...) creates a new TEMP or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before temp_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to temp_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

我想知道这两种方法有什么区别,如何把第一种的功能用第二种方法实现。
还有就是为什么第一程序无法正常运行的?
