本人用matlab编写的rels(最小二乘法），rls(递推增广最小二乘法),riv(辅助变量法递推算法)的程序，都是2阶的，稍改动就可以变成其它阶次(I use matlab prepared rels (least squares), rls (augmented recursive least squares method), riv (auxiliary variable method recursive algorithm) procedure, are 2 bands, a little change can be turned into other order)

经验模态分解分析噪声信号，带源码，初学者可参考(Empirical mode decomposition analysis of noise signal, with source code, beginners can reference)

這是一個利用butter filter 的bandstop 來濾除原始訊號中有雜訊的方法，先轉為spectrogram觀察雜訊所分步頻帶與能量，再依照要濾除的部分作bandstopa(This is a use of bandstop butter filter to filter out the noise of the original signal has a method, the first step into a spectrogram observation noise and energy of the band, then follow to filter out parts for bandstopa)

说明：  语音编解码实验例程，来自语音信号处理实验教程，包含三种编解码方法(Voice Coding and Decoding Experimental Procedure, from the Voice Signal Processing Experimental Course, contains three coding and decoding methods)

perl programming for calculating the percentage of the average values.

说明：  卡尔曼滤波器matlab源码，初学者可以作为参考，也可以直接应用(Kalman filter matlab source)

工程优化设计非线性约束序列二次规划（SQP）算法matlab代码(SQP codes formatlab)

瑞利信道的仿真。结果为信号时域的图。仿真衰落的过程。(Rayleigh channel simulation. The results of time-domain signal of Fig. Simulation of the process of decline.)

给定一个日期，求出该日为星期几（已知2002-3-28为星期四）。(Given a date, find the day of the week (known 2002-3-28 of Thursday).)

按照人名 电话号吗的格式建立电话本，再执行时把文件名作为参数。带有语音功能。(accordance with the names of persons telephone number? Format established telephone, and implementation of the document as a parameter. With voice.)
