The This snisotropic diffusion tensor filtering package is a free (GPL) MATLAB program that implements the non linear 1D 2D and 3D image and signal processing algorithm. It features an easy-to-use user interface, and a computationally powerful algorithm.

先将47168bit的宿主音频等步长分段,分为1000段，然后混沌序列选择其中的102段，对每段进行3及小波分解，挑选出绝对值最大的系数，运用嵌入公式。(47168bit first step of the host audio sub-divided into section 1000, and then select one of the 102 chaotic sequence segment, on each piece of a 3 and wavelet decomposition, the largest absolute value coefficients selected using the embedded formula.)

混沌系统的吸引子，很简单，初步学习可以看看(Attractor of the chaotic system is very simple, the initial learning can take a look at)

用MATLAB实现非线性方程的数值解法。主要有不动点迭代法，牛顿法，割线法和对称秩法的MATLAB源码。(Numerical solution of nonlinear equations with MATLAB. Fixed point iteration method, Newton, secant, and the symmetry rank of the MATLAB source.)

一个图像增强程序，用MATLAB编写，针对过曝光和欠曝光，方法简单。(An method for underexposed image processing.)

太阳黑子是人类长久以来感兴趣的问题。此处运用matlab代码对太阳黑子的记录的数据进行处理，希望能提供帮助( Using archival records,astronomers have applied Wolfer s rule to determine sunspot activity back to the year 1700. Today the sunspot index is measured by many astronomers and the worldwide distribution of the data is coordinated by the Solar Influences Data Center at the Royal Observatory of Belgium. The text file sunspot.dat in the matlab/demos directory has two columns of numbers. The first column is the years from 1700 to 1987 and the second column is the average Wolfer sunspot number for each year.)

数据归一化函数，有些matlab没有此函数，在此，上传一个函数让大家共享，谢谢(Data normalization function, some matlab does not have this function, in this, the upload function to share, thank you )
