用FAMALE.TXT、MALE.TXT的数据作为本次作业使用的样本集，利用C均值聚类方法对样本集进行聚类分析，对结果进行分析.(Use FAMALE. TXT, MALE. TXT data as the assignment is to use the data sets, using the c-means clustering method of the sample set clustering analysis, the analysis of the results. )

MemDC防止屏幕闪烁的好方法，如不使用内存DC在画图，显示时会闪烁。(memdc redraw dc)

利用STFT可以估计信号在每片短时窗内的频率得到信号的瞬时频率，该曲线由一组时间和频率相对应的点组成，反映了信号频率随时间的变化。(Using STFT can estimate the frequency of the signal in every piece of short-time window get signal instantaneous frequency, the curve consists of a set of time and frequency of corresponding points, reflects the signal frequency changes over time. )

LSI就是这样一种维数约减方法。它可以通过对“文档向量矩阵”进行解奇异值分解（SVD: Singular Value Decomposition）运算，自动计算得到一个比原始空间小得多的有效语义空间(LSI is such a dimensionality reduction method. It can be through the "document vector matrix" for the singular value decomposition (SVD: Singular Value Decomposition) operation, automatically calculated an effective semantic space is much smaller than the original space)

计算抛物线谱的一个MATLAB程序，希望对大家有帮助(A program to compute parabolic spectra.)

说明：  QPSK调制解调的程序，在AWGN信道条件下仿真，运行成功(QPSK modulation and demodulation process, the simulation under AWGN channel, run successful)

基于matlab平台，通过DCT算法来对视频进行压缩。代码包括视频分解成帧，DCT算法压缩，帧合成视频，以及综合的视频压缩M文件，可以直接仿真。有相应的图片，以及压缩前后的视频，还有原理word报告。(Based on matlab platform, through DCT algorithm to compress the video. Code includes video decomposition framing, DCT compression algorithm, frame composite video, and integrated video compression M files can be directly simulated. Corresponding images, and compressed video before and after, as well as the principle of word report.)

matlab 初学者的良师益友 一款小软件 介绍matlab的基本功用 很好啊 有需要的可以看看 谢谢支持(matlab beginners mentor a small software used to introduce the basic skills matlab ah well there is a need to look at the can I would like to thank the support)
