采矿模型 可以在准备数学建模的时候作为练习资料(Math modeling)

牛顿法求解一元三次方程的matlab 的程序，可以在十秒内求解任意一元三次方程(Newton s method for cubic equations)

介绍matlab2006a的教程及源程序(Tutorials and source code introduced matlab2006a)

说明：  一种基于RSSI的DV-HOP加权算法，该算法基于节点接收信标节点位置元组时的信号强度（RSSI）对邻居节点间跳数进行加权处理，将节点间的跳数与距离相关联，仿真试验结果证明该加权算法可大大提高定位精度。( a RSSI based weighted DV-HOP (RWDV-HOP) Localization algorithm is presented. In this algorithm the hops of adjacent node is weighted by the RSS of flooding packets transmitted between adjacent node. Our algorithm improves the localization accuracy compared with previous algorithms, which has been demonstrated by the simulating results.)

matlab实现调制解调程序，并适用matlab的绘图功能描述了具体图像实现(matlab achieve modulation and demodulation process and the application of mapping matlab functions described in the specific image to achieve)

说明：  用matlab实现的GSM TCH/EFS系统在高斯信道、瑞利信道下的性能仿真，其中用到了循环编码、卷积码、交织码等信道编码技术(Using matlab to achieve GSM TCH/EFS system in the Gaussian channel, Rayleigh channel the performance of simulation, which uses a loop encoding, convolutional codes, interleaving codes channel coding techniques)

这里给出了几个可见光通信的MATLAB程序，调制方式采用OFDM调制解调，对于可见光通信的研究者具有重要的参考价值。(Here are a few visible light communication MATLAB program, modulation using OFDM modulation and demodulation for visible light communication researchers have important reference value.)

此程序为我写得自适应控制程序，欢迎大家评阅(I write this program for adaptive control procedures, welcomed the U.S. Review)
