VLAST 8x8 using 4-QAM

kd-tree 是广泛用来处理多维寻找最近点的数据结构。该文件中是由matlab调用c++代码实现的，其中实现包括kd-tree的建立最近点的查找等。(kd-tree is kind of data structure which is widely used to find the nearest point in multi-demensions.The zip file contain matlab and cpp files.The functions implemented include kd-tree building and nearest points searching and so on.)

头文件 ”time.h” 下的函数： Clocl_t和tine_t都可以将系统的时间和日期标示为长整形。 结构类型 tm 保存分解的日期和时间元素。 Tm的结构定义如下： (Header file " time.h" function under: Clocl_t and tine_t can the system time and date indicated for the long plastic. Decomposition structure type tm save the date and time elements. Tm structure defined as follows:)

另一个matlab版本的差分进化算法，跟前面上传的有差别。(A differential evolutionary algorithm coded by matlab)

Wimax model, matlab simulation

机械优化设计主要包括建立优化设计问题的数学模型和选择合适的优化方法及程序两方面的内容.基于二次插值法的基本原理,通过实例,编写MATLAB程序进行求解,计算结果说明了二次插值法是一种求解一元函数极小点问题最优解的可行高效的方法.(Mechanical optimization design includes a mathematical model to optimize the design of the problem and choose the appropriate two aspects of optimization methods and procedures based on the basic principles of quadratic interpolation method, is solved by way of example, the preparation of MATLAB, the results illustrate the quadratic interpolation method is a function of one yuan to solve the problem of the optimal solution of the minimum point efficient way possible.)

简化的ANN程序，程序代码很少，但是预测效果相当(a simplified Ann algorithm with good performance)

image segmentation, find in other sits

采用行均值相减法抑制温度场的非线性影响，增强目标点，利用形态学方法抑制背景并保留高亮区，搜索局部极大值，利用阈值分离出目标，实现红外点目标的检测(enhancement of point target are carried out by inhibiting nonlinear influence in temperature field with line average subtracting，Inhibiting background and maintaining high brightness area are implemented by using Top-Hat operator morphological filtering，then The targets are separated off from searching for local maximum。this program realize the detection the infrared small target)
