用BP网络逼近某曲线函数，在神经网络中邮广泛的应用 是系统辨识的基础。 通过反馈来不断的调整系数，限制了最大循环次数 防止进入死循环，当然如果想要得到更精确的系数可以增大循环次数。 (Using BP network function approximation to a curve, mail is widely used in neural network is the basis of system identification. Through feedback to constantly adjusted factor, limit the maximum cycle times to prevent into dead circulation, and of course if you want to get a more accurate coefficients can increase the cycles.)

It is DMT for power line communications but low complexity at transmitters

利用matlab进行时域有限差分模拟电磁场分布的编程案例。(Matlab FDTD programming for simulation of electromagnetic field distribution.)

说明：  用matlab实现卡尔曼滤波对三状态的信号进行滤除噪声(Kalman filter with matlab the three states to filter out the noise signal)

利用PID控制算法实现曲线的拟合跟踪，分别对阶跃曲线和正弦曲线进行控制，并比较拟合的误差曲线(Using the PID control algorithm curve fitting tracking, respectively, on the step and sinusoidal curve control, and compare the error curve fitting)

此程序用于实现结构的有限元计算：将patran中的模型的bdf文件中的单元信息和节点信息保存成txt文档，在matlab中调用，就可实现刚度矩阵、质量矩阵的组装，进而有限元计算(This procedure is used to achieve the structure of the finite element method: bdf file of the model in patran unit information and node information is saved into a txt file called in matlab, you can achieve the stiffness matrix, mass matrix assembly, and then the finite elementcalculate)

说明：  遗传算法序列（GA）（全）利用matlab编写遗传代码 很有用的啊(Sequence of genetic algorithms (GA) (wide) the use of the preparation of the genetic code matlab useful ah)

《计算机程序设计艺术》重译自Donald E. Knuth(汉名高德纳)的三卷著作： The Art of Computer Programming: 1. Fundamental Algorithms 2. Seminumerical Algorithms 3. Sorting and Searching ；三卷中文名为《基本算法》、《半数值算法》及《排序与查找》。本书内容博大精深，作者因为三卷书获得美国计算机协会1974年图灵奖（该奖被国际公认为计算机科学领域的最高奖项）。(The Art of Computer Programming retranslation Donald e. Knuth (han gartner) three volumes of The book: The Art of Computer Programming: 1. The Fundamental Algorithms 2. The Seminumerical Algorithms 3. The Sorting and Searching Three volumes in Chinese, the basic algorithm, a numerical algorithm and the sorting and searching.And profound content of the book, the author for three books for the computer association in 1974 Turing award (the prize is internationally recognized as the highest award in the field of computer science).)
