matlab绘制三维Hilbert谱程序，保证可用。上传文件采用的是.txt形式，实际使用时只需要将后缀改为.m即可在matlab中运行。(matlab draw three-dimensional Hilbert spectrum procedures to ensure that available. Upload file uses a .txt form, the actual use of the suffix to .m only need to be run in matlab.)

判断一组数据服从何种分布：正态分布判，断泊松分布判断，γ分布判断，指数分布判断，rayleigh分布判断(Determine a set of data obey what distribution )

matlab学习案例，基于遗传模拟退火算法的聚类算法(the matlab case study, the clustering algorithm based on genetic simulated annealing algorithm)

基于matlab对图像进行中值滤波处理处理，另外附有自己编写的两种中值滤波算法，同时也可以使用matlab自带的median函数(median filter for image processing)

对阵矩阵的三对角化：用householder方法将n阶实对称矩阵约化成三对角形式(With the householder method to n-order real symmetric matrix into tridiagonal form )

输入一个句子后，通过点击按钮，可以得到本句子的单词个数与句子的个数(Enter a sentence, by clicking on the button, you can get the number of words in this sentence and the number of sentences)

Channel simulation for Adaptive coding modulation, BER analyzer any didigital mod with any channel code

A new concept of tracking ball has been applied of detecting the ball in one frame by finding centroid ball ,finding histogram of the ball region and correlating it with candidate s histogram (by scanning the complete image) in subsequent frames. Matching of histogram indicates presence of ball ,hence tracks it.

傅里叶变化性质在MATLAB中的实现，时域和频域对比，以及程序仿真(Fourier nature of the changes implemented in MATLAB, time domain and frequency domain correlation, and program simulation)
