用matlab追迹子午光线，处理像差问题(Meridian ray tracing using matlab to deal with the problem aberration)

传统频谱校正方法和全相位频谱校正法比较，可以看出全相位频谱校正的优势很明显(Traditional correction method and full-spectrum phase spectrum correction method of comparison, we can see the advantages of all phase spectrum correction obviously)

利用方程产生 Lorenz 时间序列，十分有用(Lorenz equations )

通过layout生成activity。需要在Constants类里面配置项目路径等信息。(Generate activity by layout.Users need to write project path in the class of Constants.)

高斯白噪声产生程序文件，直接可用有注释 对于初学者有帮助(Gaussian white noise generated files, can be annotated directly helpful for beginners)

SIMULATION FOR MOTOR STRARTING

matlab 做图像平移和旋转 用的是领域插值法 二次线性插值 另外还有一些调用matlab自带函数的编程(matlba image shift and rotate)

常用跳频，扩频信号的调制与解调，主要用于通信及数字信号处理领域(Commonly used frequency hopping, spread spectrum modulation and demodulation of the signal, mainly used in the field of communications and digital signal processing)

说明：  一个数如果恰好等于它的因子之和，这个数就称为“完数”，编写程序找出2～5000中的所有完数。(If a number is just equal to the sum of its factors, this number is called &quot complete number&quot , written procedures to identify 2 to 5000 in the number of all finished.)
