不同于普通教程烦躁的理论和使用方法的讲述，本资料提供了Matlab实际操作、程序编写的大量实例，对于了解Matlab基本用法的学习者有很好的指导作用。(Unlike the theory of general annoyance and use tutorial method described, this information provides a Matlab actual operation of a large number of examples of programming for the basic use of the learner to understand Matlab has a good guide.)

MATLAB编写的一个M文件，实现二分法求函数f在[a,b]上的一个零点，牛顿插值法(MATLAB prepared a document M, realize dichotomy for function f in [a, b] a zero, the Newton interpolation)

说明：  针对煤矿井下巷道狭长，信号多径效应明显，接收信号强度（RSSI）测距算法受井下环境影响大，定位精度低的情况，提出了一种信标节点链式部署结构下的动态RSSI测距算法，该算法以信标节点间的距离和它们间测量到的RSSI值为参考，计算巷道内实际环境下的路径衰落指数，以提高RSSI测距算法对环境的适应性。(A dynamic RSSI location algorithm is proposed based on the beacon nodes chain deployment of tunnel Wireless Sensor Networks and the algorithm takes the distance and the corresponding RSSI between the adjacent beacon nodes into account to calculate the actual path loss parameter in the tunnel, thus improving the environmental adaptation of the location algorithm. )
