效果图
图1.主界面
图2.其中一个子界面
具体步骤
1.界面设置
输入guide并选中运行
2.菜单设置（图1上方）
3.背景图片
参考https://blog.csdn.net/leo0308/article/details/82694995
4.界面跳转
在自动生成的Untitled_5_Callback末尾加一句set（其余语句均自动生成，下略）
function Untitled_5_Callback(hObject, eventdata, handles)
% hObject handle to Untitled_5 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
set(interface4,'Visible','on') ;
添加一个菜单、文本框、图、坐标轴和按钮等（对fig文件操作），都会自动生成对应的函数（对m文件操作）（如按钮为callback），写在这个函数内函数就是点击该按钮执行的语句，右击改按钮打开检查器可查看属性，修改属性后按回车保存。
4.输入提示框
指图2内的步骤数，随机种子等，添加静态文本，打开检查器，修改string属性为步骤数
输入框和坐标轴同理
5.分析按钮
分以下几步：
（1）输入框提取，设置变量名
J=get(handles.edit1,'String');
J=str2double(J);
（2）算法代码略。
（3）画图，这里坐标轴改了属性名
plot(handles.axes1,[0:js-1],v(2,1:js));
（4）输出数据到excel
xlswrite('interface4sta.xlsx',v(2,1:js),'Sheet1');
6.GUI转exe文件
参考https://blog.csdn.net/caizanhui/article/details/112582223
需要注意的是，生成的exe并不能脱离matlab运行，需要从matlab官网安装一个支持文件（不是整个matlab），文件安装速度很快，但32位系统可能不支持。
图1、图2的全部代码展示，供改错参考，直接复制无法运行，想要传输必须传输扩展名为m和fig的源文件。
