matlab 工具箱 很好的工具箱，只要能找到相应的程序就可以了(matlab pls strong helpful good well it is so good as to use this matlab pls)

基于NET和MATLAB的虚拟实验室构建，希望对大家有用(NET and MATLAB-based virtual laboratory building, we hope to be useful)

DPCM编解码的SIMULINK建模仿真(DPCM codec SIMULINK modeling and simulation)

说明：  本程序为块匹配算法的快速搜索策略，菱形搜索法，也叫钻石搜索法(This program is fast block-matching algorithm search strategy, diamond search, also called the diamond search method)

　计算机人脸识别技术( Face Reocgnition)就利用计算机分析人脸图像,从中提取出有效的识别信息,用来辨认身份的一门技术。[ 1 ]即对已知人脸进行标准化处理后,通过某种方法和数据库中的人脸样本进行匹配,寻找库中对应人脸及该人脸相关信息。人脸自动识别系统有两个主要技术环节,一是人脸定位,即从输入图像中找到人脸存在的位置,将人脸从背景中分割出来,二是对标准化后的人脸图像进行特征提取和识别。本文中介绍的PCA (特征脸)方法就是一种常用的人脸 特征提取方法。(Computer Face Recognition Technology (Face Reocgnition) on the use of computer analysis of facial image, to extract the valid identification information used to identify the status of a technology. [1] that is known to standardize treatment of face, through a method and a database of face samples for matching, search library, the corresponding face and the face-related information. Automatic face recognition system has two main technical aspects, first, face location, that is, from the input image to find the location of the face there, the faces will be split out from the background, the second is, the standard features of face images extraction and recognition. Described in this paper PCA (Eigenfaces) method is a common facial feature extraction method.)

能读取.SLP文件 来提取按照xyz轴旋转的图像(Can read. SLP is the file to extract images in accordance with xyz-axis rotation)

需将图形文件复制到D盘根目录，或修改程序中的相关文件的路径。 计算机运行可能会出现这样的警告：Warning: Function call WAVEDEC2 invokes inexact match F:Matlab oolboxwaveletwaveletwavedec2.m. > In Wnn0802 at 18 无妨，没关系的，不影响运算结果。(Need to copy files to the D graphics root directory, or modify the program in the path of the relevant documents. Computer running such a warning might appear: Warning: Function call WAVEDEC2 invokes inexact match F: Matlab toolbox wavelet wavelet wavedec2.m> In Wnn0802 at 18 anyway, it does not matter, does not affect the result of the operation.)

信号与系统实验源代码 包括：实验一 周期信号的谐波逼近，幅频相频分析；实验二 simulink信号的抽样和内插； 实验三 GUIDE二阶状态轨迹的显示；实验四 Wav信号的波形分析及频谱分析(Signals and systems including source code of the experiment: The experiment of a periodic signal of the harmonic approximation, the amplitude-frequency phase-frequency analysis experiment II simulink signal sampling and interpolation experimental GUIDE second-order three-state trajectory display experiment four Wav signal waveform analysis and spectral analysis)

说明：  这是一个相对完整的OFDM通信系统的仿真设计，包括编码，调制，IFFT， 上下变频，高斯信道建模，FFT，PAPR抑制，各种同步，解调和解码等模 块，并统括系统性能的仿真验证了系统设计的可靠性。 (This is a relatively complete simulation of OFDM communication system design, including coding, modulation, IFFT, the upper and lower frequency, Gaussian channel model, FFT, PAPR suppression, various synchronization, demodulation and decoding of modular and system performance omnibus simulation of the system reliability.)

这是个十分简单有效的程序,可以在任何加噪声的程序里运行(This is a very simple and effective procedure, any increase in noise of the program running)
