calculating signal to noise ratio

说明：  有关神经网络理论与matlab r2007的实例与应用，都是教程，(Related to neural network theory and matlab r2007 and application examples are tutorials,)

matlab版本 图论中的kruskal算法 一般C版本的比较多，这里提供matlab版本的，更简单方便使用 (Matlab code of kruskal algorithm in graph theory)

一种很容易理解的svm matlab工具箱，可用于分类，回归，并附很多示例。(A very easy to understand svm matlab toolbox, can be used for classification, regression, together with many examples.)

基于matlab的粒子滤波经典程序。实现了目标跟踪。初学者非常好用！(Based on the classical particle filter matlab program. Achieve the target tracking. Beginners are very easy to use!)

此源码中包含了电磁场中的电偶极子matlab 仿真，及微波与天线中常用到的阻抗圆图matlab仿真。(This source contains electromagnetic field in the electric dipole matlab simulation, and commonly used in microwave and antenna to the impedance circle diagram matlab simulation.)

说明：  里面有滑模控制教材的所有程序,很有参考价值(Sliding mode control materials inside all of the programs)

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, )
