为了了解系统某一状态时所处的时间，用积分方法从相平面获得时间信息。(In order to understand the time in which a state of the system from the phase plane using the following methods to obtain time information.)

该软件是利用matlab求曲线交点的源程序(The software is the intersection of the demand curve using matlab source)

dfrft离散分数阶傅里叶变换的matlab程序，适合入门(Discrete fractional Fourier transform of the matlab program, suitable for entry )

潮流准调和分析 Dd.m [DO1 dO1 DK1 dK1 DM2 dM2 DS2 dS2 DM4 dM4 DMS4 dMS4]=Dd(y,D,Y,tm,A1) 计算6个准调和分潮的振幅系数和初相角公式 aM.m [N n aa liu_u liu_v]=aM() 基础系数矩阵，目前D和d值是取用的各段数据的中间时间值，t是以中间为0左右对称取； 视差潮龄A1需要预先得知 同时本程序负责读取原始测流数据，格式为 站位名称 观测数据段数N（即大 中 小潮） 第一段起始时间YYYY MM DD HH mm ss 第一段个数n1 speed direction speed direction ... 第二段起始时间 YYYY MM DD HH mm ss 第二段个数n2 speed direction speed direction ... 第三段起始时间 YYYY MM DD HH mm ss 第三段个数n3 speed direction speed direction ...

算术编码源代码，可以编码一个字母序列，字母范围为a，b，c，e，d，( the root code of arithmatic coding ，very simple )

关于魏格纳分布的计算代码，可以得到IMF和各个特征频率以及进行希尔伯特变换。(About calculation code Wigner distribution can be obtained as well as the IMF and the individual characteristics of the frequency of the Hilbert transform.)

关于模拟退火算法的matlab源程序，希望对大家有用(matlab source code on the simulated annealing algorithm . Hope to be useful)

说明：  运用该算法可以很方便的计算出各种计算参数的均值及数据的分类！(It works for multi-dimensional Euclidean distance.)

说明：  Matlab 常用图像函数（强大，实用），上传的还是一些matlab的东西,别人给的,应该是一些图象处理比较有用的东西。(Matlab image function (strong, used the practical), upload or some Matlab thing, other people to give, and there should be some image processing is useful things.)
