LSB used in watermarking for embedding

用不同的方法来设计FIR数字滤波器,利用MATLAB来设计FIR数字滤波器.(Use different methods to design FIR digital filters, using MATLAB to design FIR digital filters.)

构造函数实现雪花分形，但是MATLAB运行当迭代次数过多会存在不足，实现较慢！(Constructor to achieve fractal snowflake, but the MATLAB run when the number of iterations too many deficiencies to implement slow!)

蒙特卡洛方法的应用算例，采用matlab编写，简单实用(Monte Carlo methods of numerical example, the use of matlab to prepare, simple and practical)

使用Matlab的M文件实现的SVPWM程序，包含调制区和过调制区两个过程，文件包含主程序和子程序，经过测试可行。(Using Matlab M-file to achieve SVPWM program consists of two processes modulation region and over-modulation region file contains the main program and subroutines, tested feasible.)

MATLAB GUI学习的一些资料，有助于GUI的学习(MATLAB GUI to learn some of the information that helps in the learning of the GUI)

 结合理论课讲解基于Matlab建立不同信道模型：高斯信道、Rayleigh信道，Recian信道及多径衰落信道模型；  给出QAM/GMSK调制方式下在上述信道模型下的误码率性能分析，分析比较两种调制方式的优缺点；  分析信道参数、信噪比对误码率性能的影响； (Based on Matlab, we construct different channel models: Gaussian channel, Rayleigh channel, Recian channel and multipath fading channel model. The error rate performance analysis of QAM/GMSK modulation mode under the above channel model is given, and the advantages and disadvantages of the two modulation modes are analyzed and compared.  Analysis of channel parameters, signal to noise ratio on the impact of bit error rate performance )

this code is written to solve non linear equation using muller method.

利用backstepping算法设计的移动机器人轨迹跟踪控制器matlab源代码，包里面有四种轨迹，分别是直线、圆、椭圆和不规则轨迹，希望能够对研究此方向的朋友有所帮助。(I write using backstepping algorithm design of mobile robot trajectory tracking controller matlab source code, there are four types of packet paths are straight, round, oval and irregular track, hope to be able to research in this direction will help a friend.)
