说明：  一个用于求圆周率pi的matlab算法。题目背景：取一长面积为1平方米的正方形白纸，在白纸的内部画一个直径为1米的圆，如下图所示。此圆恰好与正方形的四条边分别切于一点，它的面积是 pi*（1/2）^2 =pi/4 ,然后，你可以抓一大把芝麻，一粒一粒地随便地扔到白纸上。在你扔麦子的过程中可以请一位朋友帮助记录：一共扔了几次？有几次是扔在圆里面？ 实验结束后，你只须用“芝麻落在圆里的次数”除以“一共扔的次数”得到的结果就是圆的面积。则pi就是“圆的面积*4”了 当然，你扔的次数越多，结果就越精确！()

说明：  高斯光束matlab源程序，可以编译修改。(Gaussian beam matlab source, can compile changes.)

The goal of this program is to demonstrate the construction of a huffman encoding tree. The tree is represented as a binary tree using MATLAB s built in treeplot commands. Contruction of the tree as well as the huffman code book will be described in later sections.

matlab实现的动画程序：程序运行时，会看到图中的小球沿着曲线周而复始的运动。(matlab s movie:use matlab to draw a figure,which can make the figure to moving like a movie.In this program,you will see a small ball roll along the curve up an down.)

说明：  To improve the boiler drum level control system of a power plant, the three challenging issues encountered include (1) effect of ‘‘false water level’’, (2) controller parameter mismatches due to variant working conditions and (3) signal noise caused by uncertainties of drum level. In this paper, based on analyses of the drum level signal, an adaptive derivative action is presented to monitor steam flow, and thus, the effect of ‘‘false water level’’ is weakened. The uncertainties of parameter mismatches and noise are predicted by developing a Grey predictor based algorithm (GPBA). In order to resolve the three problems and further control performance, an adaptive technique is combined with the GPBA to develop an adaptive Grey predictor based method. Finally, concrete simulations give that the proposed method has obvious superiority over conventional methods.
