1、重慶科技學院數(shù)學實驗與數(shù)學軟件課程設計 課程名稱： 菜單與對話框設計 開課學期：_2014-2015-1 學 院:_ 數(shù)理學院 開課實驗室：_數(shù)學實驗與建模實驗室_學生姓名: 譚云文 專業(yè)班級: 應數(shù)13-2班 _ 學 號:_ _實驗十二 我們本次實驗做的是菜單與對話框設計，所謂菜單與對話框的設計包括在圖形用戶界面中。而圖形用戶界面是由窗口、菜單、對話框等各種圖形元素組成的用戶界面。因為在這種用戶界面中，用戶的操作既生動形象，又方便靈活，這是它的一大特點。在MATLAB中，基本的圖形用戶界面對象包含3類：用戶界面控件對象、下拉式菜單對象和快捷菜單對象，可以設計出界面友好、操作方便的圖形用戶界面

2、。其中MATLAB用戶菜單對象是圖形窗口的子對象，所以菜單設計總在某一個圖形窗口中進行。MATLAB的圖形窗口有自己的菜單欄。為了建立用戶自己的菜單系統(tǒng)，可以先將圖形窗口的MenuBar屬性設置為none，以取消圖形窗口默認的菜單，然后再建立用戶自己的菜單。對話框是用戶與計算機進行信息交流的臨時窗口，在現(xiàn)代軟件中有著廣泛的應用。在軟件設計時，借助于對話框可以更好地滿足用戶操作需要，使用戶操作更加方面靈活。為了更便捷地進行用戶界面設計，MATLAB提供了圖形用戶界面開發(fā)環(huán)境，這使得界面設計在可視化狀態(tài)進行，設計過程中變得簡單直觀，實現(xiàn)了“所見即所得”。例1一、實驗目的 1. 掌握plot菜單的方
