本文提出了一种基于独立分量分析的音频数字水印方法。嵌入水印时,对原始音频文件进行一级小波分解,在分解
得到的逼近分量中利用随机混合方法嵌入水印后进行小波逆变换形成嵌入水印的音频文件。仿真实验结果表明这种方
法的强鲁棒性和可行性。(Abstract:Audio p roduction is one of the important digital multimedias, which transmit becomes more and more convenient. To

gpsCalculate
包含三个M文件，其中ReadGpsData.m是读取导航文件，TimetoJD.m是将民用年历转换为儒略日，CalPos.m是将读取的数据计算卫星的坐标。
此程序计算结果较好。
(M consists of three documents, which is read ReadGpsData.m document navigation, TimetoJD.m is converted to civilian Julian calendar date, CalPos.m is to read the coordinates of the satellite data. Calculation of this procedure with satisfactory results.)

kmeans
k-means clustering is a method of vector quantization, originally signal processing, that is popular for cluster analysis in data mining. k-means clustering aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest mean, serving as a prototype of the cluster. This results in a partitioning of the data space into Voronoi cells.
