A Level set based interpolation algorithm for image processing which is especially helpful for beginners.

DS_CDMA通信系统的MATLAB仿真源程序，包含发射信号、QPSK调制、GLOD码扩频、解扩、解调等过程(DS_CDMA communication system simulation source of MATLAB, including emission signal, QPSK modulation, GLOD code spread-spectrum despreading, demodulation, etc. )

it is used to count the coin in the box using matlab

说明：  k-中心与qpso算法的结合，从文档中读取对象数据，没有维限制。需要设定类别数，先由k-中心计算出各类中心，然后由qpso优化，得到聚类结果，并保存聚类信息。(algorithm for k-medians and qpso combination of object data read from the document, there is no dimension restrictions. Need to set the number of categories, first calculate the k-medians types of center, and then optimized by qpso obtained clustering results, and save the clustering of information.)
