大小盘风格轮动策略,本版本暂时选取沪深300作为大盘股指数，中小板指数作为小盘股指数(Size of the disk style rotation strategy, the release time being selected as the CSI 300 index of large-cap stocks, small board index as the small cap index)

经济类的实用的时间序列分析软件包，已经是目前最好的版本了。USCD_GARCH，可以研究非平稳时间序列数据。(kind of practical time series analysis software package, is the best current version. USCD_GARCH can study non-stationary time series data.)

DCSK QCSK CS-DCSK系统仿真 以及说明 可用 经过测试 (DCSK SYSTEM)

说明：  节点重要度计算方法源代码 详细介绍了算法的应用(The application of the algorithm is introduced in detail in the source code)

混凝土配合比计算程序。可根据混凝土强度得到配合比。自己编的。参考规范为2009年之前的规范。(Concrete mix calculations. Be in accordance with the ratio of concrete strength. Their series. Reference standard for the specification by 2009.)

数学建模清华数模讲义\model3b (Mathematical modeling Qinghua digital-analog handouts model3b)

我从这里下载一个MATLAB文件来计算激光的模式，拉盖尔-高斯模式，但它不能正常工作。所以我说我自己的函数。这是很简单的功能，我希望它是有效的以及。我用它和后结果我得到了。(i download one matlab file from here to calculate the modes in laser, Laguerre-Gauss modes but it was not working properly. So i wrote my own function. It is pretty simple function, i hope it is efficient as well. i used it and post the result i got.)

采用matlab的simulink模块实现了基于矢量控制的永磁同步电动机控制系统，电机模型为matlab自带模型，SVPWM的实现则采用了模块搭建，仿真模型运行时间快，效率高，便于学习研究(Using the matlab simulink module implements the permanent magnet synchronous motor control system based on vector control, motor model for matlab own model, SVPWM implementation of the module is used to build simulation models running time, high efficiency, easy to learn study)

结合遗传算法与神经网络的图像分割,能得到分割结果的全局最优解,避免陷入局部最优.( Segmentation of image through the combining of genetic algorithm and neural network.)

MATLAB est un logiciel de calcul matriciel à syntaxe simple. Avec ses fonctions spécialisées, MATLAB peut être aussi considéré comme un langage de programmation adapté pour les problèmes scientifiques
