系统介绍了matlab编程思想，是工程师的必备选择(Matlab programming system introduces the ideas are essential for engineers)

此程序为BPSK matlab仿真源代码，如有需要请谨慎下载(This program is BPSK matlab simulation source code, if necessary, download with caution)

【转】协同过滤代码，用于推荐系统，包括基于项目和基于用户两种情况。实现基于用户和基于项目的协同过滤算法。 实验所用数据为MovieLens – a web-based movies recommender system with 43,000 users & over 3500 movies. 保存在ga.mat文件用，由于ga.test测试集过于庞大，全部用来计算的话耗时庞大，所以每次计算时随机选择部分，具体函数的使用请参照probar.m。我所得到的实验结果保存在results1-results8.mat里面。([Turn] collaborative filtering code for the recommended system, including project-based and user-based two cases. User-based and project-based collaborative filtering algorithm. Experimental data for MovieLens- a web-based movies recommender system with 43,000 users & over 3500 movies. Saved in ga.mat file with Because ga.test test set is too large, all used to calculate the time-consuming massive, so every time The calculated random selection portion, the use of the specific function, please refer to probar.m. I obtained experimental results are saved inside results1-results8.mat.)

将用matlab编译的N－R法用于潮流计算是以导纳矩阵为基础的，由于利用了导纳矩阵的对称性、稀疏性及节点编号顺序优化等技巧，使N－R法在收敛性、占用内存、计算速度方面的优点都超过了阻抗法，成为六十年代末期以后普遍采用的方法。(Matlab compiler will use the N-R method for power flow calculation is based on admittance matrix-based, due to the use of the admittance matrix of the symmetry, sparsity and node ID, such as sequential optimization techniques, so that N-R method in convergence , memory, computing speed advantages over the impedance method, the late sixties to become widely used method.)

说明：  用matlab编的小程序，希望对大家有所帮助！(using Matlab series of small programs, we hope to help!)

基于稀疏变量的欠定盲源分离，可以解决源数大于传感器数的问题，即欠定盲源分离问题。(Based on the sparse variable underdetermined blind source separation, can solve the source number is greater than the number of sensors the problems, i.e. underdetermined blind source separation.)

美国HL20航天飞机的完整动力学模型以及可视化的实时飞行仿真(U.S. HL20 completed dynamic model of the space shuttle as well as real-time visualization of Flight Simulation)

是信号处理的基础，快速扩展随机生成树算法，DSmT证据推理的组合公式计算函数。( Is the basis of the signal processing, Rapid expansion of random spanning tree algorithm, Combination formula DSmT evidence reasoning calculation function.)

此段程序描述了电偶极子在静态的情况下的电场、电势分布图。 比较简单注重在一些基本语句的使用(This procedure describes the electric dipole in the case of static electric fields, electric potential distribution maps. Relatively simple focus on the use of some of the basic statement)
