matalb微分方程的解法，对于数理方程的学习和数学建模有参考价值。(matalb Differential Equation, for the study of mathematical equations and mathematical modeling of a reference value.)

This is a code to reduce the salt-pepper noise in a figure by filtering.

说明：  matlab均值平滑滤波器（3*3模板）(matlab mean smoothing filter (3* 3 templates))

本程序可以对图象或者信号做频谱分析.简单而且容易理解.可以直接应用.(This procedure can be done on the image or signal spectrum analysis. Simple and easy to understand. Can be applied directly.)

MATLAB编的一些计算算法，里面有详细的说明，仅供参考。(MATLAB compiled some of the calculation algorithm, which has detailed instructions for reference only.)

matlab程序，气象学上画风场，可以添加标尺(matlab procedures, meteorology style games, you can add the ruler)

一个很好带阻滤波器的设计，并给出了用来滤除工频干扰的实例(A good band stop filter and filter frequency is given to an instance of interference)

对一帧图片的目标物进行特征提取，以便以后进行块匹配(On a target image feature extraction, in order to block a later match)

有序列表的插入，每次添加新数据时，保证整个列表的有序性(Into an ordered list, every time you add new data, to ensure the orderly nature of the entire list)

本代码可以实现CIC的抽取滤波功能，性能很好(This code implements the CIC decimation function, performance is very good)
