说明：  编程计算图形的面积。程序可以计算圆形，长方形，正方形的面积，运行时先提示用户选择图形的类型，然后，对圆形要求用户输入半径值，对长方形要求用户输入长和宽的值，对正方形要求用户输入边长得值，计算出面积的值后将其显示出来。(Calculate the area of graphics programming. Program can calculate the round, rectangular, square area, run-time prompts the user to first select the type of graph, and then the radius of the circle requires the user to input the value of the rectangle requires the user to input the length and width values, requires the user to input side of the square grow the value to calculate the value of the area after the show.)

本程序研究了在不同符号序列条件下，基本Gardner算法和一种修正Gardner算法的定时误差特性(This program studied the sequence of symbols in different conditions, the basic Gardner algorithm and a modified Gardner timing error characteristics of the algorithm)

说明：  针对小流域设计洪水计算中，采用推理公式求解洪峰流量Qm及汇流时间τ的方法繁琐，查算精度较低等问题，提出用牛顿迭代法求解，该方法较原图解试算法收敛快，迭代次数少，计算速度快，精度可靠。计算实例表明，用简单迭代法与牛顿迭代法计算设计洪峰流量，其结果与图解试算法完全一致。()

该程序对于遗传算法的初学者很有帮助 学习该程序基本就可以了解遗传算法的基本原理(procedures for the genetic algorithm helpful beginners learn the basic procedures can understand the basic genetic algorithms Principle)

将整个空间进行划分，变成无数的小空间，其中小空间的长度可变。(The entire space is divided into numerous small space, wherein the variable length of the small space.)

实现维纳滤波用于语音增强。第一步采用频域谱函数计算最佳的维纳滤波器，再对输入带噪信号进行滤波；第二步是在此基础上的改进，用了自适应的思想，及时根据当前帧的状态更新修正滤波器的系统函数，得到更精确的无噪语音信号。第三步是采用自适应LMS方法，在时域迭代计算滤波器系数，迭代次数足够多时可得到较准确的有用信号。(Implement wiener filtering used in speech enhancement. First step optimum wiener filter is obtained by using the frequency spectrum function, again to input the signal with noise filtering The second step is the improvement on the basis of this, with the idea of adaptive, and in a timely manner according to the current frame updates correction system function of the filter, get a more accurate without noise speech signal. The third step is to use the adaptive LMS method, iterative calculation in time domain filter coefficient, the number of iterations enough to get the useful signal accurately.)

Generalized Hurst exponent of a stochastic variable

The aim of this assignment is to use the Finite Difference Method to numerically determine the transverse electromagnetic (TEM) transmission line (TL) parameters of a line with a coupled ribbon shaped cross-section. To achieve this, a computer program was developed to perform the finite difference calculation the computer program used in this report was Matlab.
