概率统计实验源程序！这是一个学习使用概率中心极限定理的工具箱

function varargout = xiezhh4(varargin)
% XIEZHH4 M-file for xiezhh4.fig
%      XIEZHH4, by itself, creates a new XIEZHH4 or raises the existing
%      singleton*.
%
%      H = XIEZHH4 returns the handle to a new XIEZHH4 or the handle to
%      the existing singleton*.
%
%      XIEZHH4('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in XIEZHH4.M with the given input arguments.
%
%      XIEZHH4('Property','Value',...) creates a new XIEZHH4 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before xiezhh4_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to xiezhh4_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
