此为频谱分析工具箱，如寻找频谱峰值等等功能的源代码(This is the spectral analysis toolbox, such as the search for the peak spectrum function of the source code, etc.)

说明：  利用子空间方法实现盲信道均衡的matlab程序，给大家个参考(Subspace method for blind channel equalization to achieve the matlab program, give us a reference)

不错的灰度处理matlab程序 实验过 有些地方需要修改更好(good handle Matlab experimental procedure that some places need to be amended to better)

matlab经典学习教程，从入门到精通，适合初学者使用(matlab classical learning tutorials, from entry to the master for beginners)

最小平方反褶积是把地震子波压缩成尖脉冲，从而使地震记录能够直接反映地下反射系数序列(Least squares deconvolution of seismic waves are compressed into spikes, which can directly reflect the seismic record subsurface reflection coefficient series)

Localization algorithm in Matlab

动力锂离子电池二阶等效电路模型（MATLAB/simulink环境下运行）(Lithium-ion battery second-order equivalent circuit model (running MATLAB/under simulink environment))

利用matlab gds的插件 对各种几何图形进行设计(Using the MATLAB GDS plug-in to design a variety of geometric figures)

说明：  各比例微分系数下系统的单位阶跃响应，有扰动曲线，随着微分作用的加强，系统的超调量减小，稳定性极高。(The unit step response of the system with various proportional and differential coefficients has perturbation curve. With the enhancement of differential action, the overshoot of the system decreases and the stability is very high.)
