图像的边缘检测，根据靶标上圆的圆心坐标、半径把5个圆圆周上的点的坐标求出(Image edge detection, in accordance with the target coordinates of the center circle, the radius of the round five weeks on the coordinates of the points obtained)

说明：  该函数用来计算时间序列的最大Lyapunov 指数--Wolf 方法(The function used to calculate the time series of the largest Lyapunov index- Wolf method)

说明：  这个是一个关于ofdm的程序，里面有很重要的东西，希望大家多看看！(This is a study on the OFDM procedures, there are very important things, I hope we see more!)

The first purpose of this paper is to present a brief introduction to the behavior and functioning of a PV device and write its basic equation, without the intention of providing an in-depth analysis of the photovoltaic phenomena and the semiconductor physics.

说明：  music算法的实例，用于matlab编程的学习，适用于初学者，可以借鉴学习编程(The example of music algorithm is used for learning matlab programming. It is suitable for beginners and can learn from learning programming)

战胜matlab比做练习题，非常有用的学习资料，用它学习matlab，从入门到精通，面面俱到(Matlab exercises to overcome than done, a very useful learning materials, use it to learn matlab, from entry to the master, everything)

实现三相整流功能仿真!三相六开关PFC仿真(Functions to achieve three-phase rectifier simulation! Three-phase six-switch PFC simulation)

说明：  微分进化算法的完整实例，包含使用说明文档及matlab的m文件(Complete examples of differential evolution algorithms, including instructions and Matlab m files)

对信号进行小波包分解，得出能量分布图，然后根据分解结果处理信号！(Wavelet packet decomposition of signals obtained energy distribution and signal processing based on decomposition!)

一种改进的LMS算法及其在噪声对消中的应用。在分析传统定步长LMS算法和变步长LMS算法的基础上，提出了一种改进的变步长LMS算法。新算法利用瞬时误差绝对值三次方的指数形式和遗忘因子同时调整步长，更好的解决了收敛速度和稳态误差的矛盾(An improved LMS algorithm and its application in noise cancellation. In the analysis of the traditional fixed step and variable step size LMS algorithm based on LMS algorithm, a modified variable step size LMS algorithm. Absolute value of the new algorithm uses the instantaneous error and the form of cubic exponential forgetting factor while adjusting step, a better solution to the convergence speed and steady-state error of the contradictions)
