计算Allan方差，用于导航数据分析，对于学习allan方差有一定帮助(Allan variance calculation for navigation data analysis, learning allan variance of some help)

一个用simulink做的模糊PID自适应系统，FIS等都比较简单，适合初学者。通过与PID的比较曲线可以看出此系统更加优越。(A simulink do with self-adaptive fuzzy PID system, FIS are relatively simple, suitable for beginners. Comparison with the PID system curve can be seen even more superior.)

MATLAB 小波分析高级技术——书中的一些应用程序(MATLAB senior technical wavelet analysis-- Some of the applications)

傅里叶算法，用MATLAB编程，采样周期12个点。可以实现输入变量电压或电流h12个点，计算出电压或电流的有效值(Fu Liye formula;MATLAB programming; calculation)

经验模态分解以后，可以画三维的图，一瞬时频率，时间和幅值为坐标(jingyanmtaifenjie)

使用带通滤波器对图像进行处理，其中daitongfilter。m是带通滤波器函数(The use of band-pass filter for image processing, which daitongfilter. m is the band-pass filter function)

对于任意三个整数，判断其是否为一个合法的日期值。给定一个日期值，计算若干天后的日期值，(For any three integers, determine whether it was a valid date value. Given a date and calculate the value of a number of days of the date,)

信号检测与估值实验报告，写的很好哦，本人花了大量的时间(Signal detection and valuation lab report, oh well, I spent a lot of time)
