gui03.m

实现matlab很多功能的源代码

function varargout = gui03(varargin)
% GUI03 M-file for gui03.fig
%      GUI03, by itself, creates a new GUI03 or raises the existing
%      singleton*.
%
%      H = GUI03 returns the handle to a new GUI03 or the handle to
%      the existing singleton*.
%
%      GUI03('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in GUI03.M with the given input arguments.
%
%      GUI03('Property','Value',...) creates a new GUI03 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before gui03_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to gui03_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
