说明：  基于Matlab的农用机械传动性能仿真研究(Matlab-based Transmission Performance Simulation of farm machinery)

PCA可用于图像检测的盲取证方面，效果非常好(PCA can be used for blind image forensics testing, the effect is very good)

哈工大数学实验 实验源代码实验1(HIT mathematical experiment experimental source code experiment 1)

The travelling salesman problem (TSP) or travelling salesperson problem asks the following question: Given a list of cities and the distances between each pair of cities, what is the shortest possible route that visits each city exactly once and returns to the origin city? It is an NP-hard problem in combinatorial optimization, important in operations research and theoretical computer science.

DVB-T，DTMB简化的信道仿真程序。设置了三种保护间隔：循环前缀、零添加、伪随机添加。用于研究不同保护间隔下的SNR特性，附带一个不同保护间隔下的频谱显示，可看出三种保护间隔对OFDM频谱陡峭程度的影响。(DVB-T，DTMB channel simulation and spectrum display.)

It is important in detecting the edges of image.It is better than canny.

一种复杂性测度，用来计算两个信号之间的交叉样本熵。(A kind of complexity measure to calculate the entropy of cross sample)
