因子分析可在许多变量中找出隐藏的具有代表性的因子。将相同本质的变量归入一个因子，可减少变量的数目，还可检验变量间关系的假设。(Factor analysis can be found in many variables hidden with a representative factor. The same nature of the variables included in a factor, can reduce the number of variables, but also to test the relationship between the hypothesis.)

图像加密程序，基于混沌系统的MATLAB实现(Image encryption, chaotic systems based on MATLAB to achieve)

To find the vanishing point in an image.

说明：  matlab文件结合实例，实际的优化例子，很有用的(matlab file with examples, practical optimization example, very useful)

说明：  连续隐马尔可夫模型cdhmm,多用于语音识别中，在文本相关的语音识别中，识别效果很好。(cdhmm)

采用PN码作为扩频码对信号进行扩频处理，采用BPSK进行调制，在加高斯白噪声的信道中进行传输，解调，误码率等(Using PN codes as spread spectrum code to spread spectrum signal processing, using BPSK modulation, in add white gaussian noise channel transmission, demodulation, bit error rate, etc)

matlab常用函数参考，包括基本的函数和一些特殊的函数。(matlab reference commonly used functions, including basic functions and some special functions.)

Multi-level discrete 2-D wavelet transform with the Cohen-Daubechies-Feauveau (CDF) 9/7 wavelet.
