matlab例程MATLAB 6.x版的內建數據類型（Built-in data type）就有5種以上，此外還有許多其他專門設計的類（Class），如符號類、內聯函數類、控制工具包中的線性時不變模型類、神經網絡類等。就程序設計而言，MATLAB 6.x版采用了面向對象編程技術。數據和編程的改變使用戶能更簡捷而自然地解決復雜的計算問題（如符號計算問題、多變量控制系統問題、神經網絡問題）。本章內容根據MATLAB6.5編寫，但絕大部分內容適用于其他MATLAB6.x版本。
ACM試題An Easy Problem
Description
As we known, data stored in the computers is in binary form. The problem we discuss now is about the positive integers and its binary form. Given a positive integer I, you task is to find out an integer J, which is the minimum integer greater than I, and the number of 1 s in whose binary form is the same as that in the binary form of I. For example, if "78" is given, we can write out its binary form, "1001110". This binary form has 4 1 s. The minimum integer, which is greater than "1001110" and also contains 4 1 s, is "1010011", i.e. "83", so you should output "83".
