Welch功率谱密度是用改进的平均周期图法来求取随机信号的功率谱密度估计值。Welch法采用信号重叠分段、加窗函数和FFT算法等计算一个信号序列的自功率谱估计(PSD如上例中的下半部分的求法)和两个信号序列的互功率谱估计（CSD）。MATLAB信号处理工具箱函数提供了专门的函数PSD和CSD自动实现Welch法估计，而不需要自己编程。(method of power spectral density plot )

电磁场传输在介质层中折射反射波的运动传输(Electromagnetic transmission sports transmission of the reflected wave refraction in the dielectric layer)

matlab中几个非常实用的画图程序，分别用来画箭头，方形，球体，多面体，坐标系，非常实用。(matlab drawing on some very practical procedures were used to draw the arrow, square, sphere, polyhedron, coordinate system, very useful.)

video traffic using matlab

使用matlab编写的将图片转换成avi视频的源程序代码，经本人在matlab2013b测试通过，低版本不一定适用，可以更改每秒播放的图片帧数(Using matlab to convert image to avi video source program code, via oneself in matlab2013b tests pass, low version does not necessarily apply, you can change the broadcast pictures of frames per second )

It will perform the Zooming operation on input image.

关于优化的svm寻优算法，是用ga算法优化的，过几天我会上传基于布谷鸟算法的优化算法(About optimization svm optimization algorithm is ga algorithm optimization, a few days I will upload cuckoo algorithm based optimization algorithm)
