EM算法，基于期望最大化原则进行密度估计(EM algorithm, based on the expectation maximization of the principle of density estimation)

it is source code and document for image compression using wavelet

这是一个编写matlab高效代码的指南，在编程上可供参考。(This is a document of writing efficient matlab program,it s worth being refered to when you write program.)

PMSM双闭环控制，速度环采用自抗扰控制，电流环PI控制(PMSM double closed loop control, speed loop using auto disturbance rejection control, current loop PI control)

谱估计一直以来被信号处理领域的工作者所关注，该程序总结了几个谱估计算法，供大家参考学习！(Spectrum Signal Processing has been of concern to workers in the field, the program summarizes the number of spectral estimation algorithm, for your reference to learn!)

电力系统不对称电路的故障分析及计算，包括单相短路故障，两相短路故障等(Asymmetry of power system fault analysis and calculation of the circuit, including single-phase short circuit fault, such as two-phase short circuit fault)

《matlab图像处理超级学习手册》涉及面广，涵盖了一般用户需要使用的各种功能，详细介绍了matlab在图像处理方面的使用。全书共分为14章，主要包括matlab基础知识、matlab基本运算及程序设计、图形绘制、图像处理基储图像的运算、图像的变换、图像的增强、图像压缩编码技术、图像的复原、图像分割技术、数学形态学的应用、matlab图像处理在实际中的应用、matlab图形用户界面及gui在图像处理中的应用等。(" Matlab image processing super-Learning Handbook" covers a wide variety of functions covering general users need to use, detailing the use matlab image processing. The book is divided into 14 chapters, including the basics of matlab, matlab basic operations and program design, graphics rendering, image processing, image-based reservoir operation, image conversion, image enhancement, image compression encoding technology, image restoration, image segmentation technology, the application of mathematical morphology, matlab image processing in practical application, matlab gui graphical user interface and applications in image processing and the like.)

使用MVDR算法进行波束形成并处理宽带信号，该算法分频带进行处理，并最后给出了波束图。(MVDR algorithm is used for beamforming and broadband signal processing. The algorithm divides the frequency band for processing, and finally gives the beam pattern.)

只要给个输入就可以直接运行的，在次算法上可以拓展为srAPA，VSapa等方法，值得研究(Just give input can directly run in the second algorithm can be expanded to srAPA, VSapa and so on, is worth studying)

说明：  EM算法的Matlab实现，针对GMM模型(EM algorithm for GMM Model)
