说明：  此程序是基于多级最小二乘法，运用递推算法。(This procedure is based on the multi-stage least squares method, the use of recursive algorithms.)

功能：CDMA调变 multiple access b/w 2 users using DS CDMA(multiple access b/w 2 users using DS CDMA format is : cdmamodem(user1,user2,snr_in_dbs) user1 and user2 are vectors and they should be of equal length)

说明：  自适应滤波的MATLAB实现（包括LMS，LRS、NLMS等算法(Adaptive Filtering MATLAB implementation (including the LMS, LRS, NLMS algorithm, etc.)

此程序代码是用matlab编制完成，要是是用无网格方法来解决圆形巷道问题(This code is compiled by matlab, if meshless method is used to solve the circular tunnels problem)

The method works as follows. 1. For a data set with dimensionality, d, compute the variance of data in each dimension (column). 2. Find the column with maximum variance call it cvmax and sort it in any order. 3. Divide the data points of cvmax into K subsets, where K is the desired number of clusters. 4. Find the median of each subset. 5. Use the corresponding data points (vectors) for each median to initialize the cluster centers.
