LSH 和e2LSH算法，感觉hash函数不怎么好。(LSH and e2LSH algorithm, hash function is not very good feeling.)

基于灰色系统的数据预测算法实现，算法基本正确。(Based on the gray system data prediction algorithm, the algorithm is correct.)

This code is used to findout preprocessng tools of the Image.

matlab书籍 这是一本优化工具箱基础知识的书 这是本书的第一部分(it is matlab book and you can learn the basic matlab optimization and this is the first part of the book )

In this i attached matlab code for image retrieval function by finding the distance between training and testing features and arrange it in according to ascending order.

实现matlab中GUI excel与table控件的交互，内含包括uitable用法(Matlab interact with the GUI excel table controls, embedded usage including uitable)

这是一个用来对超声图像进行滤波的算法，是我按照论文自己编的，效果与论文中的一样。是stick filter。(This is the one used on the ultrasound image filtering algorithm is in accordance with papers their own series, the effect paper. Stick the filter.)

一堆沙子的横截面，可以使用 Margolus 型邻居仿真，但运动规则不同。 规则： 元胞有 2 个状态。状态= 0 是空的，状态= 1 代表沙子。 在任何时间步长，一个粒子，可以在2x2 块中向着底部运动。可能运动如下 所示。墙壁和底部将阻止粒子继续运动。 为了让该运动略有随机性，我亦补充说一项规则，有时处于下落状态的两个元胞还旋转，直到所有的动作都完成。(Cross-section of a pile of sand, you can type using the Margolus neighborhood simulation, but the movement rules are different. Rules: There are two cellular states. State = 0 is empty, state = 1 for sand. At any time step, a particle can be in the 2x2 block toward the bottom of the movement. May exercise the following. Walls and bottom to prevent the particles continue to campaign. To make the campaign a little random, I also added a rule, sometimes in the falling state of the two cell also rotate until all actions are completed.)

总体X服从非中心卡方分布，求两个参数的极大似然估计 输入：样本数据 输出：参数估计值n，v 内有详细说明(Overall X obey non-central chi-square distribution, find the two parameters MLE)
