说明：  m算子实现特征点提取 为以后的立体匹配等工作做好前期工作(Feature point extraction and matching in computer vision to achieve three-dimensional modeling Applicable to a variety of industries and research fields Wide range of applications is very important in the field of scientific research now)

当信号采样点数很少时，不能很好的恢复原模拟信号，导致原始信号中的一部分丢失。而当信号的采样点数增多到1024时，其分辨率很好，可以有效的区分信号的信息，当采样点数继续增多时，其恢复为原始模拟信号的精度越高且不丢失原始信号。(When the signal is small when the sampling points can not be good to restore the original analog signal, causing part of the original signal is lost. When the signal is increased to 1024 sampling points, its resolution is very good, can effectively distinguish the signal information, continue to increase when the sampling points, its back to the higher accuracy of the original analog signal without loss of the original signal.)

matlab实现经典的leach（无线传感器网络簇头选择协议）算法(leach algorithm)

在以往的关于多用户检测程序，给出的多是针对CDMA系统的。出于长期以来笔者对TD-SCDMA系统应用研究，在这里我进行了一些修改(In previous procedures on the multi-user detection, given mostly for the CDMA system. For a long time writer on the TD-SCDMA system application, where I made some changes)
