此文件包含跳频信号的生成和脉冲干扰信号的生成，可以结合二者产生跳频脉冲信号(This file contains the frequency hopping signal generation and pulse interference signal generation, you can combine the two to produce a frequency-hopping pulse signal)

跳频信号的调制解调过程，代码和短时傅里叶变换，代码比较详细(FH signal modulation and demodulation process, code, and short-time Fourier transform, the code in more detail)

FLOW AROUND A SQUARE FDM is used to solve Vorticity Stream Function

calculating the square root of A by Newton method used to calculate the root of A by the method of Newton: usual and the modified method

这类控制器在大偏差范围内利用模糊推理的方法调整系统的控制量U，而在小偏差范围内转换成PID控制，两者根据事先给定的偏差范围自动实现。(This kind of controller in the big deviation range by using fuzzy reasoning method to adjust the system control quantity U, and in small deviation range NaZhuan with PID control, both, according to a given skew range prior to implementation.)
