说明：  基带信号通过高斯信道和瑞利信道的误码率的计算和仿真，并分别与各自的理论误码率曲线相比较(Baseband signal through AWGN channel and Rayleigh channel bit error rate calculation and simulation, and separately with their respective theoretical BER curves compared)

Matelab Primer，原版英文资料，不错，感兴趣的同学可以下载看看(Matelab Primer, the original information in English, well, interested students can download to see)

说明：  自己写的一个基于肤色模型的人脸检测的matlab代码。( I write a face detection based on skin color model with matlab.)

说明：  用matlab实现SVM，并与BP神经网络进行对比(Implement SVM, with matlab and compare it with BP neural network)

通过重心法确定光斑图像的中心。根据个像素的灰度值和所在的位置乘积和总面值作比，进而求得重心。(Through the center of gravity method to determine the center of the image spot. According to the gray-scale pixel value and the location of the product and the total for more than face value, and then get the focus.)

脉冲编码调制（PCM）用于在数字传输媒体上传送模拟信号，在PCM中，首先对模拟信号以高于其带宽两倍的奈奎斯特率进行采样，然后对所得样本进行量化。采用不同量化级别生成的PCM编码会影响接收器重建模拟信号的质量。 (Pulse code modulation (PCM) for the media in the digital transmission of analog signal transmission in the PCM, the first analog signal to more than the Nyquist rate of twice the bandwidth sample, and then to quantify the samples. Using different quantization level generated PCM coding receiver will affect the quality of the reconstruction of analog signals.)

当前的很多海洋数据都是海量数据，传统的ftp下载费时费磁盘，因此，openDAP方式越来越多，通过opendap可以选择直接需要的时间、空间范围内的资料。nctoolbox结合matlab实用，效果非常好的opendap工具包(NCTOOLBOX- 20130305 Full instructions and documentation at: http://code.google.com/p/nctoolbox/ We are in the progress of moving the project hosting here to github.com. Brief summary: *Prequisites *Matlab R2008a+. You can verify the version of Matlab by typing: version *Java 6+. You can verify the version of Java used by Matlab by typing: version( -java ). *The version returned should start with Java 1.6 . If it starts with Java 1.5 you can try updating the Matlab JVM: http://www.mathworks.com/support/solutions/en/data/1-1812J/ or use the older nctoolbox-20091112 version of this toolbox. )
