This is Matlab code for clustering using Self Organizing Map

In wireless sensor network, residual energy of node is very important criteria. Life of wireless sensor network depend the energy of node. In most of the application, the nodes are battery operated. So it is very important to select the parameters like nodes deployment in network, size of packet, etc. In work,analyze node’s energy with respect to packet size, distance, time and also how much data can be transmitted. And finally we will conclude for the effective value of these parameters.

基于蚁群算法的路径规划改进方法，适合各种机器人路径规划(Improved method for path planning based on ant colony algorithm, suitable for a variety of robot path planning)

说明：  系统参数辨识，用增广最小二乘算法实现。对书中的程序进行了改进：由于噪声是未知的，虽然我们模拟了系统的随机白噪声，但进行辨识时必须对噪声进行估计，见程序45行和53行。(System parameter identification, with the extended least squares algorithm. Procedures for improving the book: Because the noise is unknown, although we simulate a system of random white noise, but to identify the noise must be estimated, see the program of 45 lines and 53 lines.)

非线性材料反饱和吸收理论拟合，可以给出材料的非线性吸收Z扫描曲线(theoretical fit to reverse saturable absorption)

自己写的遗传算法程序，对初学者来说很实用，可以运行！(very good！)

利用matlab实现gps的单点定位，需要下载n文件与o文件(Using Matlab for gps single point positioning, you need to download the n file and o file.)

matlab编程（第二版）国外经典入门教材，每章后面有详细的试题，首次加入附录A和B，对于matlab初学非常有帮助！可以进行自我测试，翻译的也比较精准，对于英语程度不够看原版书籍的同学很有帮助！(matlab Programming (Second Edition) foreign classic primer for matlab,can be very helpful for the freshman!)
