matlab实验6图形用户界面设计

1、实验6. 图形用户界面设计一、 实验目的1. 掌握图形对象属性的基本操作；2. 掌握菜单及对话框设计、建立控件对象的方法。二、 实验环境1. 计算机2. matlab7.x三、 实验说明1. 正确操作，认真观察；2. 实验学时：2学时；3. 学会使用help；4. 保存整理实验结果，提交实验报告。四、 实验内容1.设计如教材P374 图1所示的菜单，并在此基础上增加选项：可以改变曲线的颜色，可以改变窗口背景颜色。 2.（选做）采用图形用户界面，从键盘输入参数a、b、n的值，考察参数对极坐标曲线的影响。五、 实验程序及结果1.figure('Color',1 1 1,'P
