matpower4.0b2用来计算潮流，比以前的版本多了连续潮流(matpower4.0b2 used to calculate the trend, more than the previous version of the continuous flow)

用matlab实现的基于颜色特征的图像检索系统。(Using matlab to achieve the color-based Image Retrieval System.)

采用五点差分格式解决椭圆问题，这里是3个详例。(Using a five-point difference scheme to solve elliptic problems, here are three detailed examples.)

单相信号的锁相功能实现（PLL），自动跟踪单相电网信号。(Single-phase signalof thelock-infunctions to achieve(PLL),automatic trackingof single-phasepowersignals.)

数字控制系统是一种以数字计算机为控制器去控制具有连续工作状态的被控对象的闭环控制系统。因此，数字控制系统包括工作于离散状态下的数字计算机和工作于连续状态下的被控对象两大部分。我的课题的数字部分（PID）仿真由相应的离散传函实现，运用数字PID对被控对象实行准确控制。通过调节比例（P）、积分（I）、微分（D），使对象的输出达到预期的效果。(Digital control system is a kind of digital computer for the controller to control a continuous state of the object and closed loop control system. Therefore, the digital control system, including work on the discrete state of the digital computer and work in a continuous state of the plant is two parts. My topic of digital section (PID) simulation by the realization of the corresponding discrete transfer function using the digital PID control of the plant is implemented accurately. By adjusting the ratio of (P), integral (I), differential (D), so that the output of the object to achieve the desired results.)
