matlab gui画李萨如图形

李萨如图形，是一种美妙的数学图形，可以用MATLAB的GUI实现。下面是一个简单的MATLAB GUI程序，可以绘制出李萨如图形。

function lisajous_gui
% 创建一个GUI窗口
hfig = figure('Name','Lissajous Curve','NumberTitle','off',...
    'MenuBar','none','ToolBar','none','Units','normalized',...
    'Position',[0.3,0.3,0.4,0.4],'Color',[1,1,1]);

% 创建一个绘图区域
hax = axes('Parent',hfig,'Units','normalized','Position',[0.1,0.2,0.8,0.7]);

% 创建两个滑动条控件
hslider1 = uicontrol('Parent',hfig,'Style','slider','Units','normalized',...
    'Position',[0.1,0.1,0.4,0.05],'Min',0,'Max',10,'Value',1,...
    'SliderStep',[0.01,0.1],'Callback',@slider_callback);
hslider2 = uicontrol('Parent',hfig,'Style','slider','Units','normalized',...
    'Position',[0.5,0.1,0.4,0.05],'Min',0,'Max',10,'Value',1.5,...
    'SliderStep',[0.01,0.1],'Callback',@slider_callback);

% 创建文本标签
htext1 = uicontrol('Parent',hfig,'Style','text','Units','normalized',...
    'Position',[0.1,0.15,0.4,0.05],'String','Frequency X');
htext2 = uicontrol('Parent',hfig,'Style','text','Units','normalized',...
    'Position',[0.5,0.15,0.4,0.05],'String','Frequency Y');

% 绘制李萨如图形
x = 0:0.01:2*pi;
while true
    freq_x = get(hslider1,'Value');
    freq_y = get(hslider2,'Value');
    y = sin(freq_x*x);
    z = cos(freq_y*x);
    plot(hax,y,z,'LineWidth',2);
    axis(hax,[-1,1,-1,1]);
    pause(0.01);
end

% 滑动条回调函数
function slider_callback(~,~)
    drawnow;
end

end

运行上述程序，会弹出一个GUI窗口，包含两个滑动条控件和一个绘图区域。通过调整滑动条的值，可以改变李萨如图形的频率。
