牛顿拉夫逊法编制的潮流计算程序，很实用，是很好的学习资料(Newton-raphson method of power flow calculation program, very practical, is a very good learning materials)

用matlab编写的神经网络预测代码，可以达到很好的预测效果！(predictived programmer using ANN)

说明：  完整版纯电动汽车Matlab/Simulink仿真模型，包括电池模型、电机模型等，下载后可以直接运行(Full version of Matlab / Simulink simulation model of pure electric vehicle, including battery model, motor model, etc.)

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(RSSI-based positioning, known to launch the node transmission signal strength, the receiving node according to received signal strength, transmission loss calculated using the theory or experience loss of signal propagation model will spread into the distance and then calculate the location of the node)

通过输入x和输出y来估计系统的传递函数模型(Through the input x and output y to estimate the system transfer function model)

用分布傅里叶计算硅波导中的非线性薛定谔方程，考虑硅波导中色散及非线性损耗(solution of NLSE(two pulses propagate in silicon waveguide) using split step fourier method)

对QPSK解调系统完美建模，其中通过改变码元速率和载波频率，再计算相应的环路滤波器的参数，即可实现多种QPSK模型的解调，且该模型可通过SYSTEM generator进行量化，从而生成ISE能直接使用的HDL代码。 matlab版本：2007a(Perfect for QPSK demodulation system modeling, which by changing the symbol rate and carrier frequency, and then calculate the corresponding parameters of the loop filter, QPSK demodulator can achieve a variety of models, and the model can be quantified by SYSTEM generator thereby generating ISE HDL code can be used directly. matlab version: 2007a)

针对Zemax2003版，可以读取Zemax的光线追迹数据，即*.zrd文件便于后期处理；(this program is designed to read*.zrd file for zemax2003)

用matlab实现对语音信号的短时分析，包括清音和浊音的判决，基音周期的估计。(Using matlab to realize short-time speech signal analysis, including the voiceless and voiced the decision, pitch period estimation.)
