说明：  利用matlab实现的时频分析，很好，很强大！(Using matlab to achieve the time-frequency analysis, very good, very powerful!)

任意输入年，月，日，通过输入日期查看它是该年的第几天(Any input year, month, day, it is the first few days)

this is a code for pca based face recoqnition ,nurl based programming .

input 3 point get a circle

一个关于超高频信号的仿真，由雷电波及正弦曲线组成，并给出了FFT波形及分析(A simulation of UHF signals, consisting of a sine curve by lightning spread, and gives waveform and FFT analysis)

自己做的双目标定的MATLAB标定实例，附带图像和仿真程序！(Make their own calibration of the binocular calibration of MATLAB examples, incidental images, and simulation program!)

基于Li模型的水平集图像分割方法，无需重新初始化，提高了图像分割的效率。(Li model based on the level set method of image segmentation, without reinitializes the, improve the efficiency of the image segmentation. )

其余混沌的数字图像处理，应用msb的置乱方法，由于msb 对图像的贡献最大，所以对msb 的置乱会产生很好的置乱效果。(Chaos remaining digital image processing, application msb Scrambling method, due to the contribution of the image msb largest, so msb Scrambling will have a very good scrambling effect.)

贪食蛇，蛇头是蓝色的，挺好玩的，在turbo c下运行(Tanshichi, snakeheads are blue, very good play, in running turbo c)

程序对天线中的一种重要类型： 半波、全波、三倍半波天线波瓣图 进行了仿真和三维成像。有助于对天线中波瓣图的理解。(Program is an important antenna types: half-wave, full-wave, three times the half-wave antenna lobe pattern simulation and three-dimensional imaging. Contribute to the wave antenna lobe pattern of understanding.)
