lms算法实现单波束形成，线阵单波束形成，(linear array signal beamforming )(lms algorithm for single beamforming line array beamforming, (linear array signal beamforming))

matlab的基础知识，大好基础，实验论证很重要。(matlab basic knowledge, excellent basic, experimental verification is very important.)

基于matlab将商标与文字分割，选定阀值，先进行次分割，在进一步优化(Matlab-based trademarks and text segmentation, the selected threshold, the first for sub-division, in further optimization)

小波算法用于频率突变的检测，已调试成功可以使用(Wavelet algorithm for the detection of the frequency break)

龙格库塔法，计算方法作业，matlab源代码，内有说明(Runge-Kutta method, calculation methods work, matlab source code, there are instructions)

画图时，将图形局部放大，很实用的代码，以前上传过一个m文件，上传错误了，现修正。(When drawing the graphic enlarged, very practical code previously uploaded an m file upload error, now corrected.)

一阶直线双倒立摆系统的可控性研究 要求在SIMULINK上建立精确模型，并封装子系统（标准模块）(An order straight double inverted pendulum system controllability study)

自抗扰控制器在实际使用时有多个需要整定的参数,由于控制器参数多,又无法确定参数作用方向,因此参数整定困 难,为实际使用自抗扰控制器带来不便。本文利用MATLAB软件仿真分析控制器及参数,寻求参数整定规律,简化整定过 程,对实际应用自抗扰控制器具有较大的意义(There ADRC in actual use multiple needs tuning parameters, as the controller parameters many, it can not determine the parameters of the role of direction, parameter setting sleepy Difficult to actually use ADRC inconvenience. In this paper, MATLAB software simulation analysis controller and parameters, parameter tuning laws seek to simplify tuning over Cheng, the practical application has a greater significance ADRC)
