HYSTERESIS

说明：  WGS84到BJ54坐标转换的四参数模型，可以求出四参数和转换坐标(WGS84 coordinate transformation to the BJ54 The four parameter model, four parameters can be calculated and converted coordinates)

无线传感器网络分簇路由算法，很经典的，适合初学者练习使用(Clustering routing algorithms in wireless sensor networks, very classic, suitable for beginners to use )

极力推荐，PKU-Matlab课程的学习的PPT，很适合初学者。(Highly recommended, PKU-Matlab courses of study on the PPT, it is suitable for beginners.)

说明：  《现代通信系统（mmatlab版）第二版》所有源代码(C ontemporary Communication Systems Using Matlab)

It can show the lines of corresponding points in two images for input points. If you have sift function, then you can utilize this function.

在图像处理实验中，有时需要对图像进行精确质量因子的JPEG压缩，而photoshop和一般的图像处理软件并不具备，本程序利用matlab实现该功能，并支持批处理(将待处理图像放入src文件夹，dst文件夹为输出)(In image processing experiments, sometimes the need for accurate image quality factor of JPEG compression, and photoshop and general image processing software does not have this program using matlab realize this function, and supports batch processing (image to be processed into the src folder, dst folder for output))

Solving Non linear Schrodinger Equation in Optical Communication

it will compute the echo cancellation using thew subadaptive filter with main filter length 256 and sub adaptive filter length 64

基于maglab/simulink平台设计的利用duffing振子检测微弱正弦信号，非常好的一个源程序，自己亲自调试，运行在matlab2012b上没有问题，仿真步长0.01s,采用RK四阶算法。若有问题，欢迎指教(Based maglab/simulink platform using duffing detect weak sinusoidal oscillator signal, a very good source, personally commissioning, operation without problems on matlab2012b, simulation step 0.01s, using the fourth-order RK algorithm. If questions, please advise)

一种使用GMM（Gaussian Mixture Model）聚类方法,亲测，好使(A clustering method using GMM (Gaussian Mixture Model).)
