说明：  由Cranfield大学的CaoYi教授编写的数独游戏。数独是风靡全球的智力游戏，本代码采用matlab实现基本的数独游戏功能。(By the Cranfield University, prepared by Professor CaoYi Sudoku. Sudoku is a popular puzzle game around the world, the code using matlab to achieve the basic function of Sudoku game.)

这个例子示出了充放电时的超级电容器的模式。该电路示出了与电池超级电容器的一个简单的杂交。超级电容器被连接到降压/升压转换器和电池连接到升压转换器。电池的功率由一个速率限制器块，因此瞬态功率由超级电容器供给到DC总线限制。(This example shows the supercapacitor model during charge and discharge. The circuit illustrates a simple hybridization of a supercapacitor with a battery. The supercapacitor is connected to a Buck/Boost converter and the battery is connected to a Boost converter. Power of the battery is limited by a rate limiter block, therefore the transient power is supplied to the DC bus by the supercapacitor.)
