本程序主要用于时间序列的去趋势算法，也就是常说的DFA。(here is a program to estimate the DFA of a time series)

说明：  计算均方误差MSE信噪比SNR峰值信噪比PSNR绝对平均误差的matlab函数(Calculate the mean square error MSE, SNR is the peak signal to noise ratio PSNR absolute average error of Matlab functions)

多因子量化选股策略，包括数据导入，分组，回测分析(Multi-factor stock selection strategies to quantify, including data import, grouping, backtesting analysis)

说明：  资料为基于BP基于BP神经网络的人脸识别源码（matlab），是课程设计做的一个课题，效果还不错，配备有测试显示界面，比较直观！(The data is the source code of face recognition based on BP neural network (matlab), which is a subject of curriculum design. The effect is good, equipped with test display interface, which is more intuitive!)

is a program which counts the number of primes between 1 and N.

：根据内蒙古四子王旗某地2007年逐月平均风速袁选取设计风速为6m／s，根据某型号300 W交流永磁发电机的输出功率特性。利用Matlab编写的叶片优化设计程序，设计了300W水平轴风力发电机叶片。通过风轮与发电机的匹配，调整叶片参数，使之在小风时具有较高的风能利用系数，提高风力机的效率，在大风时具有较低的风能利用系数，从而达到大风时限速保护的目的。(: According to Inner Mongolia as a 2007 monthly average wind speed Yuan select the design wind speed to 6 m/s, according to a Model 300 W output power characteristics of permanent magnet alternator. Leaves written in Matlab to optimize the design process, design 300W horizontal axis wind turbine blades. The wind wheel generator matching adjust the blades parameter, so that has a high wind energy utilization coefficient of small wind, improve the efficiency of the wind turbine in high winds has a lower coefficient of wind energy utilization, so as to achieve high winds speed limit protection purposes.)

OCT信号模拟 很理想化 但对初学者帮助较大(OCT signal simulation is ideal for beginners but for more help)
