本程序计算金属包覆平板波导TE模等效折射率，然后计算其光场分布(This program calculates metal-coated plate waveguide TE-mode effective refractive index, and then calculate the optical field distribution)

自己写的利用SVM分离器来识别印章。水平有限，欢迎指正。(Write my own use of SVM separator to identify seal. The level is limited, welcome to correct. )

简单的OFDM的均衡程序，采用的是ZF（迫零均衡），效果较好。(OFDM-equalization process simple, using the ZF (zero forcing equalizer) is better.)

本程序基于MATLAB编写，用于加密一幅彩色图像，通过将图像分解为RGB三通道，并且用颜色索引发完成图像的加密，程序中包含了解谜代码(The program based on MATLAB, is used to encrypt a color image, through the image is decomposed into RGB three-channel, and complete the image encryption with color hair, understand the enigma code were included in the program)

这是一个用matalb语言实现的FIR滤波器的源代码，直接可以运行，已经经过本人调试通过，对于信号处理的同行有帮助。(this is a matlab program that compute the fir filter and it was been tested by myself.)

画板素描源码程序，根据画板底色与图像的颜色差异判断，对图像进行轮廓的素描。(Sketchpad sketch source program, according to the background and image color difference Sketchpad judgment sketch the outline of the image .)

说明：  本教程提供了使用MATLAB的实践性指导，它基于MATLAB6.0版，内容由浅入深，特别是本书对每一条命令的使用格式都作了详细而又简单明了的说明，并配备了例题加以说明其用法，因此，对于初学者自学是很有帮助(The Guide provides practical guidance to the use of MATLAB, which is based on MATLAB6.0 edition, the content of easy-to-digest, especially the book on the use of each command formats are explained in detail and simple description and sample questions to be equipped with its usage, therefore, self-study is very helpful for beginners)

说明：  由于matlab提供了一些很有用的计算方法 但是大部分用户只用到其中一部分的功能 所以写了一个包括解方程，矩阵计算，排序功能的代码(As matlab provides some very useful method but most users only use part of the function it was a including solving equations, matrices, and sorting code)

Gaussian mixture model to subtract background

射线追踪,包含了起点和终点的射线函数，对于地震传播研究具有重要意义！(Raytracing in a v(z) world. The toolbox contains functions forshooting fans of rays and functions for tracing rays with specific start and end points. General multi-bounce rays with any number of mode conversions can be traced. Automatic routines for P-P and P-S primaries in shot-gather geometry are provided for convenience. Any recording geometry can be used but most functions vectorize (e.g. are most efficient) for shot-gather geometry. Only traveltimes and rayparameters are detemined, not amplitudes. In these routines, the velocity models should be considered as "background" models. This means that the depths at which flections and mode conversions occur are dependent of the depths given as layer boundaries in the velocity models. Velocity models are specified by a vector of velocities and a same-size vector of depths. The j th velocity is in effect from the j th to the j+1 th depth. The bottom of the model is assumed at infinite depth. Thus v=5000 and z=0 specifies a cons)
