基于UWT变换的去噪，利用的是硬阈值来设置阈值门限的(UWT transform based denoising, using the hard threshold to set the threshold value threshold)

说明：  helps to classify and segment the given signal using Markov models

说明：  机器人仿真例程，主要关于动态行走机器人极限环稳定性分析 (Robot simulation routines walking robot is mainly concerned with the dynamic stability analysis of limit cycles)

AWGN信道设计与仿真熟悉加性高斯白噪声(AWGN)信道，学习Matlab相关编程知识及AWGN信道的设计与仿真实现。(AWGN channel)

说明：  阶梯图绘制的MATLAB程序。需要的来下载。(MATLAB step of mapping procedures. Need to download.)

Matlab画平滑曲线的两种方法（ 拟合或插值后再用plot即可） 自然状态下，用plot画的是折线，而不是平滑曲线。有两种方法可以画平滑曲线，第一种是拟合的方法，第二种是用spcrv，其实原理应该都一样就是插值。下面是源程序。(You can then use the plot) Natural state, with the plot is a line drawing, instead of a smooth curve. There are two ways to draw a smooth curve, the first one is the fitting method, and the second is to use spcrv, in fact, the same principle should be that the interpolation. Here is the source.)

这是一个利用MATLAB利用PCA实现的简单分类程序，对于模式识别的初学者学习PCA知识并进行仿真会有很大帮助，其中male.txt和female.txt是训练样本，test.txt是测试样本，分类效果非常好。(This is a use of MATLAB to use a simple classification of the PCA implementation process, the PCA pattern recognition study for beginners and simulation of knowledge would be of considerable help, and one of male.txt samples female.txt training, test.txt is the measurement, very good classification results.)
