说明：  BP算法客运量预测，十分详细的好资料，值得参考(Passenger Volume Forecast BP algorithm, a very good detailed information, it is also useful)

仿MATLAB矩阵C++运算库,包括加、减、乘、除、点加、点减、点乘、点除、赋值、转置、rank、det、eig、svd、pinv、power等的运算。inv运算使用pinv运算。最难实现的是非方阵的除法。(MatLab Matrix simulator)

This program calculates Approximate Entropy of a given time series.

4QAM、16QAM、32QAM、64QAM、128QAM、256QAM星座图映射，map、频偏估计算法(4QAM, 16QAM, 32QAM, 64QAM, 128QAM, 256QAM constellation mapping, map, frequency offset estimation algorithm)

说明：  使用交叉熵算法，对组合优化问题，逐步逼近最优解完成寻优(Using cross entropy method to optimize the problem)

说明：  几个模式识别的作业程序，自己写的。望指教哦，内容有感知器算法、多类感知器算法以及K均值算法(Several pattern recognition procedures, wrote it myself. Advice Oh look, the contents of perceptron algorithm, multi-sensor algorithm, as well as K-means algorithm)

matlab NURBS 工具箱，应用于matlab中NURBS曲线、曲面的设计. (NURBS toolbox used in MATLAB, used to the design of NURBS curves and surfaces.)(matlab NURBS (NURBS toolbox used in MATLAB, used to the design of NURBS curves and surfaces.))

希尔伯特变换hilbert得到的解析信号，并对变换结果进行傅里叶变换，观察频谱分布(Hilbert transform to obtain the analytic signal, and transform the results of Fourier transform, observe the spectrum distribution)

采用最速下降法查找最小值，采用H终止准则，计算时间很快，很适合初学者使用(Steepest descent method using the minimum search using H termination criteria, the computation time soon, it is suitable for beginners to use)
