MATLAB实现对录音信号的滤波，包括低通，高通和带通，以及时域和频域分析(MATLAB realize filtering of audio signals, including low-pass, high pass and band-pass, as well as the time domain and frequency domain analysis)

分数阶统计是现代统计信号处理的重要内容，这里是alpha、beta分布的情况，仿真程序(Fractional statistics is an important content of modern statistical signal processing, where alpha and beta distribution emulator)

有matlab语言编程求解有关一种热传导方程的数值计算方法(a program which is a version of fem_50 for the time-dependent heat equation, by Jochen Alberty, Carsten Carstensen, Stefan Funken)

功能：用BFGS算法求解无约束问题：min f(x) 输入：x0是初始点，fun,gfun分别是目标函数及其梯度； varargin是输入可变参数变量，简单调用bfgs时可以忽略它， 但是其他程序循环调用时将会发挥重要作用 输出：x,val分别是近似最优点和最优值，k是迭代次数。(Function: BFGS algorithm for unconstrained problem: min f (x) Input: X0 is the initial point, fun, gfun each objective function and its gradient varargin variable parameter is the input variable, it can be ignored when a simple call bfgs , but other programs will play an important role when the cycle is called output: x, val are approximate optimum and the optimal value, k is the number of iterations.)

matlab用hough变换检测圆的程序，经过检测可以运行良好(matlab using hough transform circle detection procedure, after testing can run a good)

TM波照射导体圆柱，根据电场积分方程求表面电流。(TM-wave radiation cylindrical conductor, under the electric field integral equation for surface currents.)

一种新型的智能控制器，分为定值控制和伺服控制两种情况，被控对象为超大纯滞后对象，通过与PID控制的比较可以发现此新型智能控制器的优点(A new type of intelligent controller is divided into fixed value control and servo control both cases, the plant pure time delay for the large, by comparison with the PID control can find the advantages of this new type of intelligent controller)

说明：  这是一个关于小波阈值图像去噪的程序，通过对分解后的系数各层进行不同的阈值处理，最后得到去噪后图像。(It s about a wavelet threshold program well worth beginners reference! )

基于余弦变换的分块自适应水印，希望对你有帮助。(Cosine transform-based block adaptive watermark, you want to help.)

本算法能够按照两种策略生成并绘制随机图，但是对于生成的随机图的属性分析不够完善，从代码中能够看出作者并没有完成本算法关于“平均路径长度”、“聚类系数”和“平均度”三个属性的求解。(The algorithm is able to follow two strategies to generate and draw random graph, but for the properties generated random graph analysis is not perfect, it can be seen from the code of the algorithm is not complete on the "average path length", "clustering coefficient" and "the average degree of" solving the three properties)
