说明：  MATLAB求解偏微分方程 很详细 算例很多(MATLAB Solution partial differential equations in great detail)

Program for Image Halftoning by Floyd Method: The input gray image will be converted into halftone image of same size using Floyd s Error Diffusion Method.

这是有关正弦波频率估计的几种算法，包括过零点检测，rife算法，music算法，levensen法，周期图法等7种不同算法。(This is several algorithm for frequency estimation of sinusoid, including zero crossing detection, rife algorithm, music algorithm, levensen method, periodogram method 7 different algorithms.)

finding sift use matlab

包括对轴的各种操作，可以拿来用在自己程序中。 普遍适用于仿真和作图的操作。(Including a variety of operating shaft can be brought to use in their own programs. Generally applied to simulation and mapping operations.)

金融时间数列的基本处理程序代码和函数使用实例(Examples of financial time series basic handler code and function)

这两个是通信中基本仿真程序，一个是单边带调幅和双边带调幅的对比，另一是使用希尔伯特滤波器进行的单边带振幅调制解调．(these are two basic communication simulation program, is a single-sideband AM band and bilateral AM contrast, Another is the use of Hilbert's single sideband filter amplitude modulation and demodulation.)

本程序对两种固定步长和一种变步长最小均方误差算法的权值收敛进行了仿真，结果表明变步长的算法效果更优。(This programme compare LMS algorithm with VSLMS algorithm. The result indicate that the latter is better.)

根据双馈电机的数学模型，编写双馈电机S函数(s function of DFIG)

说明：  该函数用来计算时间序列的最大Lyapunov 指数--Wolf 方法(This function is used to calculate the maximum Lyapunov index time series- Wolf method)
