自己编写的matlab中编辑个人模块的S-函数方法，通过这个模块可以实现输入信号变为原来的10倍(Imagecut.rar matlab edit personal module function method of S- this module can be realized by the input signal into a 10 times )

对基于四阶累积量的MUSCI算法进行去冗余，把多余的冗余数据剔除，在保持良好分辨率的基础上也降低了运算复杂度。(Fourth-order cumulant-based algorithm to the MUSCI redundant, removed the extra redundant data, while maintaining good resolution also reduced on the basis of computational complexity.)

负责火星的一个低轨道空间站的设计。为简化结构，该空间站由一系列密闭的立方体（airtight cubical modules ACM）组成，这些ACM曾连接在一起。困扰你的一个问题是致命的病菌也许留在火星的上层大气中。因为空间站有时需要在上层大气中飞行，所以急需在ACM的各个接触面进行额外的防护，无论是边对边还是面对面，连接是密闭的，所以没有细菌能够进入。一个ACM与另外一个ACM共享的面不需要防护。如果在每个ACM每个面上都加防护，花费巨大。因此，需要知道ACM额外防护的确切面数目(Responsible for the design of a low-orbit space station on Mars. In order to simplify the structure of the space station by a series of closed cubes (airtight cubical modules ACM) composed of these ACM had together. One problem is bothering you deadly germs might stay in the upper atmosphere of Mars. Because the station is sometimes necessary to fly in the upper atmosphere, so urgently needed in all contact surfaces of the ACM additional protection, either face to face or side-to-side, the connection is closed, so no bacteria can enter. An ACM ACM shared with another surface does not need protection. If you have added protection on each side of each ACM, costly. Therefore, the need to know the exact number of additional surface protection ACM)

美国建模大赛 gerrymand问题的源代码有注解 代码比较简单 使用模拟退火法求解(code with annotation of model of gerrymanding(MCM),the result is obtained by using annealing algorthm)

用模最大值法提取小波脊，该例中又两条小波脊，所以是多脊提取。同时又施加惩罚函数，控制lamda的值，可以得到较为平滑的小波脊。( using maximum modulus extract wavelet ridge, the case has two wavelet ridge, it is a multi-ridge extraction. At the same time to impose the penalty function to control the value of lamda,the extracted ridge can be relatively smooth .)
