two methods of calculating eucledian distance are shown in the m files

奇异值分解用于英文文本检索，画出频率矩阵第一奇异值向量和第二奇异值向量的分布图( a fast retrieval algorithm for English texts is proposed. First of all, the English texts are mapped into frequency matrixes of order 26 and the dimensions of texts representation space are reduced through Singular Value Decomposition. Second, it fuses the features of the first singular value component and the second one, and then gets the complex feature vectors which reflect not only the statistic frequency but also the sequential structure of letters. )

盲源信号分析kernel-ica,amari_distance,chol_gauss,contrast_emp_grad,contrast_ica,demo_dernel_ica(kica for kernel-ica,amari_distance,chol_gauss,contrast_emp_grad,contrast_ica,demo_dernel_ica)

说明：  关于MATALAB的书籍文章很经典值得一看解压后必须使用超星浏览器观看(MATALAB article on classic books worth a visit after decompression must use a browser Chaoxing Views)

该程序可以用于语音信号的倒谱运算，其他一维信号也适用(The program can be used for speech signal cepstrum computing also applies to other one-dimensional signal)

针对leach协议 采用matlab仿真(Leach agreement for the use of matlab simulation)

说明：  用于实现语音中的对消噪声，本程序用matlab实现(For the voice in noise cancellation, the program achieved with matlab)

matlab GUI历来收到大多数学者的重视，本人编写了一些简单的GUI案例，供大家学习。(Matlab GUI has received the attention of most scholars, I write some simple GUI case, for everybody to learn.)

可对.txt文本进行霍夫曼编码，并计算其压缩率(Can. Txt text Huffman code, and calculate the compression ratio)

This code shows you how perform various boolean operation on sets using level set functions.
