这个文件包含了正弦调频信号的魏格纳威利分布以及经过平滑和加窗后的伪魏格纳威利分布和平滑伪魏格纳威利分布(This file contains a sinusoidal FM signal of the Wigner distribution and Na Weili after smoothing processing window of the pseudo-Wigner-Na Weili smoothed pseudo-Wigner distribution and the distribution of Na Weili)

说明：  能够清晰的分析线性调频信号的频谱特性，能够很好的帮助理解lfm信号(Can clear analysis of linear FM signal spectrum characteristics, can be very helpful in understanding LFM signal)

用MATLAB写的体彩七位数计算每位上各个数字出现次数的小程序(Written using MATLAB Ticai 7 calculated for each different figure on the number of occurrences of small programs)

this is a pegasis related code.

对正弦信号进行FFT变换 画频谱图，进行频谱分析，可以计算出信噪比(Sinusoidal signals of paintings transform FFT spectrum chart, spectrum analysis, signal to noise ratio can be calculated)

对输入的语音信号运用短时能量函数进行去静音，然后把去掉静音帧之后的信号进行重组。(remove the mute of the speech signal (using short-term energy function), and then remove the signal mute frame after restructuring.)

用于adaboost初学入门,有需要可以看看,比较简单,容易看懂(For the beginner of learning the adaboost)

应用MATlAB语言处理数字信号与数字图像(MATlAB language applications of digital signal processing and digital images)

二维FDTD程序，采用PML边界s 用pml和mur分别计算j=1处的Hz(i,1).计算空间扩大到400*400，不加边界，运行相同的时间步(2D FDTD procedures, Application of the PML's border with pml and mur calculated j = 1 Hz of (i, 1). for the space to expand to 400* 400, without borders, running the same time step)
