confusion_matrix

A set of functions to calculate Hu s seven invariant moments. Good accuracy. Written for my Project work

说明：  matlab中s函数的详细介绍及实用例题。(matlab s function in detail and practical examples.)

含噪语音的语音增强，包换多种算法的去噪效果对比，最后集中在一个操作界面上。(Speech enhancement in noisy speech, noise effect contrast to replacement of several algorithms, finally concentrated in one operating interface.)

fdtd计算无限长圆柱导体散射问题，可以计算RCS，包含解析解，此代码经过我自己的修改，与网络版本不同，更加好用(fdtd calculate infinite cylindrical conductor scattering problem, you can calculate RCS, it contains analytical solution, this code through my own changes, and network versions, easier to use)

激光谐振腔不同初始光强和相位分布下不同腔型下光振幅和相位模拟(Laser resonator with different initial light intensity and phase distribution of different cavity amplitude and phase of optical simulation)

说明：  用matlab实现拟合的几个例子源码， ％x,y应是原始数据，下面的数据仅是为了说明问题而自设的示例数据。(Matlab fitting used to achieve a few examples of source code, x, y should be the raw data, the following data only to illustrate the problem of sample-based data.)

利用扰动观察法实现光伏电池的最大功率点的跟踪(Perturbation and observation method using photovoltaic cells to achieve maximum power point tracking)

Bit error rate equalizer, paper. Very easy implemetation

说明：  对比了dv-hop基本算法，和加入pso后得算法。由于结果是随机产生的，不能保证每次得结构都能提高，但大部分时候，比基本算法得定位准确度好。(DV hop algorithm is compared with PSO algorithm. Because the results are generated randomly, it can not be guaranteed that every time the structure can be improved, but most of the time, the positioning accuracy is better than the basic algorithm.)

说明：  关于上面的扩频程序的具体介绍。 (spreading on the above specific procedures introduced. On top of spreading the specific procedures introduced.)
