Windpower technology dates back many centuries. There are historical claims that wind machines which harness the power of the wind date back beyond the time of the ancient Egyptians. Hero of Alexandria used a simple windmill to power an organ whilst the Babylonian emperor, Hammurabi, used windmills for an ambitious irrigation project as early as the 17th century BC.

prony算法,复指数函数的线性组合来描述等间隔采样数据的数学模型。(prony algorithm，Linear combination of mathematical models to describe the complex exponential function equally spaced sampling data)

正交信号，反相信号，开关信号的蒙特卡洛仿真(Quadrature signal, inverting the signal Monte Carlo simulation of the switching signal)

设计一个模拟信号（几个不同频率简谐信号之和，再加一个白噪声） 用不同的采样频率把信号离散（满足和不满足采样定理）， 画出信号波形； 分别作信号的谱分析（幅值）；对比采样频率的影响； 选用不同窗函数对同一个信号作谱分析，比较分析。(signal process using matlab)

Matlab code for record tool for speech recognition

说明：  这是仿真powell算法的简单程序，已经调试过了，效果不错，请大家多提宝贵意见(This is a simple simulation algorithm powell procedures, have been debug, good results, please mention the valuable advice)

用matlab编写BP神经网络实现数据信号分类，本例为语音信号分类(BP neural network with matlab write data signal classification, classification of speech signal in this case)

实现超指数盲均衡算法，隐含了信号的高阶累积量信息 (realize the SEI equalization algorithm and uses the high order cumulates of signals)

基于L阵列的一些二维DOA估计,其中一些算法与最新的文章有着直接对应关系(Based on L array of 2-d DOA estimation, some algorithm has direct correspondence with the latest article)

针对DEM的建模问题，将高程看作区域化变量，应用地质统计学中普通克里格研究了一个山区高程空间变异分析及其插值。(DEM for modeling will be seen as a regionalized variable elevation, application of ordinary kriging in geostatistics research a mountain elevation spatial variability analysis and interpolation.)
