一个控制托盘图标位置的例子(-An example of controling the ico position of tray)

给定一个样本集exset，样本数为M，每个样本点是N维向量，对于给定目标点d，d也为N维向量，要从exset中找出与d距离最近的k个点(k<=N)(knn code c++)

说明：  用matlab实现的神经网络Hopfield网络算法，初步编写，欢迎指正(nertural network)

本代码使用matlab实现理想高通滤波增强图像(Matlab to achieve ideal high-pass filtering to enhance the image)

合成地震记录是用声波测井或垂直地震剖面资料经过人工合成转换成的地震记录（地震道） 合成记录的制作是一个简化的一维正演的过程，合成记录F(t)是地震子波S(t)与反射系数R(t)褶积的结果。(Synthetic seismogram is sonic or vertical seismic profile data after conversion into synthetic seismograms (seismic trace) the production of synthetic seismogram is a simplified one-dimensional forward modeling process, synthetic seismogram F (t) is the seismic wavelet S (t) and the reflection coefficient R (t) the convolution results.)

本文主要是介绍了EKF与UKF的基本原理及其区别，主要适合讲课和作业运用(This paper introduces the basic principles of its distinction of EKF and UKF for lectures and operating use)

设雷达信号是码宽为0.5微妙，中心频率是10MHz的7为巴克码2PSK信号，接收的雷达回波中频采样频率为为40MHz，中频进行正交下变频。假设在13.5km处有一个点目标，仿真该雷达的脉冲压缩处理。 已通过测试。 (Let the radar signal is yards wide 0.5-subtle, the center frequency of the the Buck the code 2PSK signal, the received radar echo IF sampling frequency of 10MHz to 40MHz, IF quadrature down-conversion. Assuming the 13.5km at a point target simulation of the radar pulse compression processing. Has been tested.)

说明：  实现数字图像滤波,能够较好的实现图像的滤波霸霸工傀要革故鼎新(to filter digital image)

采用稀疏矩阵的PQ分解法潮流计算程序（依据《电力系统计算》一书附录用C语言编写，使用方法、变量名称都与书上一致）(Decoupled load flow)

该论文介绍了电磁场积分方程的无网格数值计算方法，传统的体积分数值计算都需要进行网格剖分，网格剖分的好坏直接影响着数值计算的速度和精度，很多精细结构很难用网格来模拟，无网格技术可以很好地解决此类问题！(This paper describes the meshless numerical method electromagnetic integral equations, numerical integration of traditional body calculations require meshing, meshing a direct impact on the speed and accuracy of numerical calculation, many very fine structure difficult to simulate with the grid, no grid can solve this problem!)
