图形句柄的应用、可视化界面的设计

1、实验7 图形句柄的应用、可视化界面的设计一、实验目的1、掌握图形句柄的应用；2、采用figure， uimenu， uicontextmenu函数设置窗口界面；3、掌握可视化界面GUI的设计应用。二、实验内容1、运行以下程序：（1）体会pause、close命令的作用。Pause作用是使程序暂停,直至用户按任意一个按键.Close作用是关闭图形窗口（2）语句9的作用是什么？将标题颜色变为红色，字号大小25。（3）12语句的作用是什么？获得屏幕尺寸（4）13语句的作用是什么？修改其中的属性值，看运行结果如何？设置窗口在windos界面的位置，及窗口大小。（5）修改14语句中的属性值，看运行结果如

2、何？分别代表距离该窗口边线的上下左右的距离百分比（6）16，17语句的作用是什么？设置x，y坐标轴的范围。x=-5:0.1:5; % 1h=plot(x,3*x+sin(x)-exp(x); % 2set(h,'color','r','linestyle',':','linewidth',5) % 3title('曲线图','color','g') % 4pause % 5set(get(gca,'xlabel'),'string',&

5、单“仿真”。在“仿真”菜单下建立“绘制曲线sin(x)”以及“绘制曲线cos(x)”并能实现相应的曲线绘制功能。（4）建立一个与sin(x)、cos(x)相联系的快捷菜单，用以控制曲线的线型（实线，虚线）、线宽（加宽，变细）以及曲线颜色（红色，绿色）。（5）建立关闭窗口菜单。图 1figure('Menubar', 'none', 'Name', 'ÔËÐнá¹û','NumberTitle', 'off', '

12、“关闭窗口”菜单：仿真：在仿真菜单下建立绘制曲线sin(x)、绘制曲线cos(x)子菜单并实现绘图功能。关闭窗口：实现关闭窗口功能。（3）建立快捷菜单，实现以下功能：在网格菜单下设计子菜单：加网格，去网格，并实现其功能；在坐标菜单下设计子菜单：标注坐标（x轴，y轴），去标注坐标；在标题菜单下设计子菜单：加标题（仿真曲线，红色字体大小为20），去标题。（4）在设计菜单时，注意复选框spearator above this item、enable this item在程序运行中的作用。spearator above this item作用为分割线enable this item作用是是菜单生效 f
