matlab實驗6圖形用戶界面設(shè)計

1、實驗6. 圖形用戶界面設(shè)計一、 實驗目的1. 掌握圖形對象屬性的基本操作；2. 掌握菜單及對話框設(shè)計、建立控件對象的方法。二、 實驗環(huán)境1. 計算機2. matlab7.x三、 實驗說明1. 正確操作，認真觀察；2. 實驗學時：2學時；3. 學會使用help；4. 保存整理實驗結(jié)果，提交實驗報告。四、 實驗內(nèi)容1.設(shè)計如教材P374 圖1所示的菜單，并在此基礎(chǔ)上增加選項：可以改變曲線的顏色，可以改變窗口背景顏色。 2.（選做）采用圖形用戶界面，從鍵盤輸入?yún)?shù)a、b、n的值，考察參數(shù)對極坐標曲線的影響。五、 實驗程序及結(jié)果1.figure('Color',1 1 1,'P
