说明：  内部集成多种算法，对图论学习的帮助那就不用说了，祝你们好运(A variety of internal integration algorithms, graph theory to study the help of it, needless to say, and I wish you good luck)

利用CFD软件，采用雷诺应力模型分别计算了300型和250型水力旋流除砂器的内流 场，得到了2种水力旋流除砂器的轴向、径向、切向速度及压强的分布曲线。通过对所得结果的 分析，发现模拟结果基本符合旋流除砂器的运行规律。比较2种旋流除砂器的内流场，表明改进 的300型水力旋流除砂器的结构及分离能力优于原来250型水力旋流除砂器，为水力旋流除砂器 的优化设计和选型提供了可靠的设计依据。(use CFD software, Reynolds stress model used to calculate the respective 300-and 250-type sander hydrocyclones the flow field, been two kinds of hydrocyclones sander axial, radial and tangential velocity and pressure in the distribution curve. Based on the results of the analysis, the simulation results are consistent with the Cyclone sander operating rules. Comparing two kinds of Cyclone sander within the flow field, show improved 300 Desanding Hydrocyclones the structure and separation capacity than the original 250-hydrocyclone sander, Desanding Hydrocyclones for the optimum design and selection provided a reliable basis for the design.)

协同过滤代码，由于需要，但是找不到好的代码，所以花了一天时间写的代码，希望对大家有帮助！(recommend system)

大部分都是数学建模的资料,大家要多多支持啊!(are mostly mathematical modeling of information, we have to be generous support ah!)

frequency response of first order discrete time systems.

matlab处理图像代码，很不错，值得看看(matlab image processing code, very good, worth a look)

Matlab中几个经典的编程例子，很适合初学者(Matlab, the programming of several classic examples, it is suitable for beginners)

本程序利用Matlab软件仿真了QPSK+瑞利信道及高斯信道，对比分析结果。(This procedure used Matlab software simulation QPSK+ the Rayleigh channel and the Gauss channel, the contrastive analysis result.)
