遗传算法相关编程，可以直接拿过过来应用，非常经典的程序。(GA-related programming, applications can be directly took over, very classic procedure.)

robotearth本体定义文件，定义了类别概念和关系等(The OWL ontologies used in the KnowRob system, about robot concept and class.)

用椭圆低通滤波器对语音信号进行滤波处理，实现降噪处理(The elliptic low pass filter is used to filter the speech signal, and the noise reduction processing is realized.)

说明：  计算并绘制直方图. 绘制直方图的方法有很多，在此我用MATTAB中的一些代表性的绘制选项，使用函数bar\imhist(use function "bar" )

WSN 质心定位算法 Centorid Algorithm 加经典参考文献 A: 如果接受节点接收到的包数目与发送节点发送的包数目的比值大于CM_threshold,则这两个节点视为邻居节点 未知节点利用邻居锚节点进行定位，没有邻居锚节点的未知节点无法定位。 B: 如果接受节点接收到的包数目与发送节点发送的包数目的比值大于CM_threshold,则这两个节点视为邻居节点 未知节点一旦被定位就充当起锚节点的功能，向周围邻居发送自己的估计坐标信息 未知节点把已经定位的未知节点与锚节点同等对待 C: 如果接受节点接收到的包数目与发送节点发送的包数目的比值大于CM_threshold,则这两个节点视为邻居节点 有邻居锚节点的未知节点只利用邻居锚节点进行定位，没有邻居锚节点的未知节点才利用已经定位了的邻居未知节点进行定位。(WSN centroid localization algorithm Centorid Algorithm A: If you accept the received packet node number and the number of packets sent by the sending node ratio greater than CM_threshold, then these two nodes as neighbors Unknown node using the neighbor anchor nodes to locate, no neighbors anchor nodes and unknown nodes can not be located. B:   If you accept the received packet node number and the number of packets sent by the sending node ratio greater than CM_threshold, then these two nodes as neighbors Unknown nodes are positioned on as soon as the function of anchor nodes to send their neighbors estimated coordinate information Unknown unknown node to node already positioned anchor nodes treated equally C: If you accept the received packet node number and the number of packets sent by the sending node ratio greater than CM_threshold, then these two nodes as neighbors Of the unknown neighbor anchor node the neighbor nodes are only positioned anchor nodes, )

说明：  一些iceemdan的所需程序，用于信号处理等方面。(Some iceemdan required programs)

syms函数rrrrrrrrrrrrrrrrrrrrrrrrrrrrrr(the syms functions rrrrrrrrrrrrrrrrrrrrrrrrrrrrrr)

图像处理中用到的一些代码，在MATLAB环境下开发的。(image segmentaion.)

最速下降法，优化算法的一种，具有二次收敛性，若目标函数为二次正定函数，经有限步可达到极小点(Steepest descent method, an algorithm with quadratic convergence, if the objective function is quadratic positive definite function can be achieved by the finite step minima)
