Mathematica 的函数大全，在水木清华上被评为精华。里面列举的函数命令大多比较常用。(Collection of functions of Mathematica, SMTH was named in essence. Which lists most commonly used function of command.)

MATLAB软件实现计算有限长序列的DFT和IDFT函数的程序，另有一个实例(MATLAB software calculation of finite-length sequence of DFT and IDFT function procedures, while an example of)

利用MATLAB展示风玫瑰图,进行气象分析，统计分析，以及风资源分析(plot windrose pictures by matlab)

matlab中随机生成囧字，非常不错的动画(matlab randomly generated embarrassing word, very good animation)

余弦分析采用最小二乘法，以适应一个正弦波的时间序列。余弦分析通常用于生物时间序列分析，演示predictible的节奏。这种方法可用于一个不平等的间隔时间序列。(Cosinor analysis uses the least squares method to fit a sine wave to a time series. Cosinor analysis is often used in the analysis of biologic time series that demonstrate predictible rhythms. This method can be used with an unequally spaced time series.)

说明：  仿真模拟信号，并提取瞬时信息的算法，通过实践可以哦(Simulation signals, and extract the instantaneous information algorithm, through practice you can Oh)
