说明：  俄罗斯方块（可以玩游戏），但主要是对喜欢matlab、正在学习matlab编程的同学提供一个参考的例子。程序一千行左右。程序放在txt文件中，将文件考入到matlab（需要建一个.m的文件，拷入其中）中运行即可。
(Tetris (play the game), but like matlab matlab programming students are learning to provide a reference example. Program about a thousand lines. Program on the txt file, the file was admitted to Matlab (need to build a file of m copyed which) Run.)
