matlab应用接口编程设计基础，术语应用的扩展(matlab application interface programming design based on the term application extension)

说明：  基于RSSI的定位，已知发射节点的发射信号强度, 接收节点根据接收信号的强度, 计算出传播损耗, 利用理论的或经验的信号传播模型将传播损耗转化为距离, 然后再计算出节点的位置。(Based on RSSI positioning, the transmitting signal strength of the transmitting node is known, and the receiving node calculates the propagation loss according to the received signal strength. The propagation loss is converted into distance by using the theoretical or empirical signal propagation model, and then the position of the node is calculated.)

Using matlab bit plane decomposition. It contained 2 versions. One is using functions. One is using matlab codes.

”BP.m“文件是BP神经网络整个模型的源程序； “train.fig”是训练时最后得到的图片； “程序运行的人口数量原始数据.fig”是预测结果绘制的图； “程序运行时matlab命令窗口的内容.txt”是运行程序是在matlab命令窗口显示的东西； “程序运行完产生的数据.mat”是程序运行完毕产生的数据。 .bmp文件和.fig文件一样()
