用Matlab作图时，特别是所作的图是要用于科研论文投稿时，对图的大小有一定要求。但用缺省设置作图时，图的大小不能控制，而且常常有大块的空白。本程序可控制图的大小和位置，并能自动去掉空白。(Using Matlab mapping, especially of the map is to be used for scientific research papers submission, the size of the map has a certain requirement. However, when using default settings mapping, map the size of control, often have large gaps. This procedure can control the map size and position, and can automatically remove blank.)

用matlab对照片进行频域变换，并进行简要分析比较DCT、DFT、WH等方式重构的图像与原始图像之间的差别，并写出报告(use matlab to perform the frequence transform and use DCT/DFT/WH to rebuild the picture, analysis the difference and report)

曲柄滑块机构的机构组成，速度方程以及匀角速度运动学仿真框图(Of the institutions of the slider-crank mechanism, the rate equation and the constant angular velocity kinematics simulation diagram)

为了准确地对监控场景中的运动目标进行语义上的分类，提出了一种基于聚类的核主成分分析梯度方向直方图和二又决策树支持向量机的运动目标分类算法。(In order to accurately monitor the movement of scene targets semantic classification, the clustering based on kernel principal component analysis of gradient direction histograms, and two and a support vector machine decision tree classification algorithm of moving objects.)

此代码展示了在mimo系统中分别用ML MMSE ZF和MMSE-SIC检测算法的不同误码率曲线(This code shows the mimo system respectively ML MMSE ZF and MMSE-SIC detection algorithm different BER curves)

数字信号处理综合设计 利用windows下的录音机录制一段自己的话音，时间控制在1秒左右；并对语音信号进行采样，理解采样频率、采样位数等概念。(Digital signal processing integrated design Using Windows, making a video recorder under his voice, time control in 1 seconds And the voice signal sampling frequency sampling, understand concepts, sampling digits. )

本仿真程序实现了正交频分复用系统的调制与解调。(This program simulates orthogonal frequency division multiplexing（OFDM）system.)
