用有限差分模拟高斯脉冲在自由空间传播，运行该脚本，你会得到一个表面，它是由脉冲在1微米的步骤传播。 (Using the finite difference simulation of Gaussian pulse propagation in free space, run the script, you will get a surface, it is spread by the pulse in steps of 1 micron.)

一个很有用的基于稀疏的信号处理工具箱，包含有多种算法。(a useful toolbox based on sparse signal processing )

optimization codes for matlab

二维功率谱密度换算一维功率谱密度的程序,对表面质量的计算尤为使用(two dimensional power spectral density to one dimensional psd)

说明：  matlab 经典算法包括很多非常经典的matlab算法。值得一看。(matlab classical algorithms, including many classic matlab algorithm. Worth a visit.)

Circuit domain transformation parameters

用于将层速度转化为动校正速度，使用在地震勘探研究中。(Computing the Vnmo from Vstrata for horizontal strata in seismic research.)

说明：  串联的H桥多电平变换器的协调控制方法的研究、建模与仿真。内容写的很详细(Research on H-bridge multi-level converter series coordinated control method, modeling and simulation. Content written in great detail)

说明：  一篇有关扩展卡尔曼滤波中噪声协方差取值测量的外文文献(Identification of process and measurement noise covariance for state and parameter estimation using extend kalman filter)

这一段源代码为瑞利衰落信道的实现，代码比较简单，适合初学者学习(This section of the source code for the realization of Rayleigh fading channel, the code is relatively simple, suitable for beginners to learn)
