本代码是利用matlab实现dct变换，作用后效果可见 (This code is to use matlab to achieve dct transform, the role can be seen after the effect )

经典数据挖掘算法，Matlab实现，是Word版。(classic data-minning algorithms using matlab.)

说明：  该代码可以仿真直接扩频系统不同正弦幅度下误码率的的大小(Simulation of bit error rate of direct spread spectrum system)

说明：  利用matlab软件实现对于具有一定重叠度的两幅影像（左右影像）进行金字塔算法匹配。(Matlab software for use with a certain overlap of the two images (left image) to the pyramid algorithm is matching.)

This code is used in the course Digital Communications. It simulates 16QAM mode with different SNRs.

MATLAB CODE FOR DECODE AND FORWARD

说明：  基于四阶统计最大化的盲源信号分离技术，可实现复数形式的盲源信号分离，观测混合信号需要大于等于源信号个数(Blind source signal separation technology based on four-order statistical maximization can realize the separation of blind source signal in plural form, and the need to observe mixed signal is greater than equal to the number of source signal.)

含19个小区的多小区系统大尺度衰落建模。(With 19 multi-cell cellular system by the decline of large-scale modeling.)

求解TSP问题，即在N个城市中各经历一次回到出发点，使所经过的路程最短。采用连续的Hopfield网络实现以5个城市为例的TSP问题。(TSP problem, that each of the N cities experiencing a return to the starting point, so that the shortest distance elapsed. Use continuous Hopfield networks to five cities as an example of the TSP.)

有关matlab的数值计算求导方法，对以后数值计算的求导很实用。(About matlab numerical calculation method of derivation, for subsequent numerical derivation is very practical.)
