两个matlab编写的经典游戏 数独和俄罗斯方块 ( MTETRIS Matlab Tetris (v1.1) To play this game, type: MTETRIS Controls (use numpad): [4] Left [5] Spin [6] Right [2] Drop alternatively, [A] Left [W] Spin [D] Right [S] Drop [Ctrl+P] Pause/Unpause During the game, use the game menu to set difficulty and to enable/disable sound effects. Only one game can run at a time. mtetris was written and tested on Matlab 5.3 (R11), but may work with as early as Matlab 4.0 without changes. )
