此文档涵盖了Matlab初学者和有一定基础的学者，在编程过程中遇到的指令方面的集合。(This document covers the Matlab have a certain foundation for beginners and scholars, in the programming process encountered in a collection of directives.)

说明：  matlab拟合二维高斯曲面,直接拷贝运行(matlab fitting two-dimensional Gaussian surface, the direct copy operation)

该程序可以画出三维的运动轨迹，可以看到轨迹的前视图，还可以对轨迹进行旋转等(The program can draw three-dimensional trajectory, you can see the front view of the track, the track can also be rotated, etc.)

用LU分解法解线性方程组Ax=b。用牛顿法求非线性方程f(x)=0(With the LU decomposition method of solving linear equations Ax = b. Using Newton s method for nonlinear equation f (x) = 0 )

用于大矩阵，采用矩阵运算优先速度的dtw算法实现。 dtw:Dynamic time warping 动态时间弯曲算法(dtw:Dynamic time warping )

数字图像处理，利用matlab开发环境进行编程实践。(Digital image processing using matlab to program development environment practice.)

用此程序中您可以控制鼠标并单击或双击您想要的位置，而不必鼠标！这些项目有利于教学软件。这些程序中还用到C库！(With this program you can control mouse and click or double click anywhere you like without touching mouse ! also upload keyboard_simulation for controlling keyboard without touching it ! These programs is good for teaching softwares. In these programs c library is used ! )

DCT域音频水印算法代码，用于音频媒体版权的保护(Audio Watermarking Algorithm for DCT-domain code)

Matlab编程实现简单的流体替换以及前后合成地震记录对比，含word文档及图示说明。(Matlab programming simple fluid replacement and synthetic seismograms before and after comparison, including word documents and illustrations.)

说明：  ER: is the code for the Error Ratio metric performance for multi-objective optimization problems: ERtest is the code for no threshold value, whuile ERtest2 code with a thresho d value defined by the user
