This code can be use in inversion of seismic data.

说明：  m序列产生matlab仿真，simulink系统仿真(m sequence generator matlab simulation, Simulink system simulation)

将方波周期信号展开成傅里叶级数并生成3次，5次，8次，10次谐波(Expand the square wave into a Fourier series of periodic signal and generates 3 times, 5 times, 8 times, 10 times harmonic)

全面的matlab/simulink例题!!(Matlab simulink modeling examples,usefull, powerful!!)

说明：  由simulink搭建的前向差分PID控制系统(Simulink erected by the PID control system prior to the difference)

基于matlab的边缘提取，边缘检测的一般算法包括Canny算子、Prewitt算子、Sobel算子、Roberts算子。(Matlab-based edge detection, edge detection algorithms, including general Canny operator, Prewitt operator, Sobel operator, Roberts operator.)

EEGLAB 中文帮助文档，很有用的， 有需要的同学可以下载下来看看(EEGLAB Chinese help documentation, very useful, there is a need for students to be able to download it and see)

sampencandApEn.m 为证明 样本熵 较 近似熵 更准确的程序 fast_ApEn1.m sampenc.m 为sampencandApEn.m的子程序(sampencandApEn.m sample entropy to prove more accurate than the approximate entropy procedure 3.fast_ApEn1.m sampenc.m subroutine is sampencandApEn.m)

对应汪荣贵基于暗原色先验模型的Retinex算法程序，程序是我自己通过学习他的论文根据论文编写的，大家可以看看。(WANG Rong-gui dark colors correspond to a priori model based on Retinex algorithm, the program is my own by studying his thesis based on papers prepared, we can see.)
