求去噪之后信号的信噪比，发给大家共同探讨(For denoising the signal to noise ratio after the signal, issued to everyone to explore)

本工具包给出了反问题计算常用的正则化参数确定，求正则化解等方法。非常有效，是难得的一款好软件包(The kit gives the calculation of inverse problem regularization parameter commonly used to determine, find the regularized solution and other methods. Very effective, a good package is a rare)

国外用MATLAB编写的多维分形分析断裂结构的程序。在地质建模中有潜在用途。(A MATLAB® program based on the Hou algorithm for estimation of fractal dimension and multifractal spectrum of fractures is presented. The program performance was tested with many synthetical fractals and field data. )

说明：  常用数学建模美赛数据来源网站，可以帮助大家更快查找数据(base on the matlab compitation that we can study)

说明：  Matlab简单教程，能学习一些最基本的操作(Matlab simple tutorial to learn some basic operations)

matlab 的最新工具包，包括遗传算法，粒子群算法，总之 与现代优化算法一书中较为匹配(MATLAB tool box )

matlab和C交互程序，MATLAB计算，C设计界面。(interactive program of matlab and C,matlab is suitable for computing and C is suitable for interface design.)

由于实际信道中的多径和阴影效应，单个认知用户频谱感知的性能受到影响，因此需要靠不同用户间的协同频谱感知来对抗多径和阴影效应。本设计要求在文中采用一种协作机制，即两用户进行协作频谱感知，提高主用户的检测率，减少检测时间，并且得到捷变增益。要求给出仿真结果。(As the actual channel of the multi-path and shadow effect, a single user of spectrum sensing of cognitive performance are affected, it needs to depend on collaboration between different users of spectrum sensing to combat multipath and shadow effects. The design requirements in the text using a cooperation mechanism, namely, two user collaborative spectrum sensing, to improve the detection rate of the primary users, reducing detection time, and get agility gain. Required to give simulation results.)

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 )
