说明：  自适应中值滤波器的滤波方式和传统的中值滤波器一样,都使用一个矩形区域的窗口Sxy,不同的是在滤波过程中,自适应滤波器会根据一定的设定条件改变(即增加)滤窗的大小,同时当判断滤窗中心的像素是噪声时,该值用中值代替,否则不改变其当前像素值,这样用滤波器的输出来替代像素(x,y)处(即目前滤窗中心的坐标)的值。(Adaptive Median Filter for filtering methods and the same as the traditional median filter, use a rectangular area of the window Sxy, different in the filtering process, the adaptive filter in on certain Presumed Conditions change (an increase of ) filter window size, while when the judge is the filter window center pixel noise, the median value is used instead of, or does not change its current pixel value, so that the output with a filter to replace the pixels (x, y) Office (that is, coordinates of the current filter window centered) values.)

产生信号加噪声，并且把它MTI,MTD,脉冲压缩。(Generating a signal plus noise, and put it MTI, MTD, pulse compression.)

比例电磁铁仿真，有磁滞回线，电感变化。 输入为电压，输出为力。(Model of solenoid)

在matlab下实现使用双频组合观测值对观测值中的周跳进行探测，附有实验数据文件(In matlab combination to achieve dual-frequency observations using the observed values ​ ​ of the cycle slip detection, with the experimental data file)

基于matlAB的切比雪夫、FFT频谱分析、FFT线性卷积、巴特沃斯程序代码，自己编写的(Based on The Chebychev matlAB the FFT spectrum analysis, FFT linear convolution code Butterworth own written)

基于matlab的二阶微分动力学的智能体flocking数值模拟，其中每个智能体的动力学用微分方程来描述，给出每个个体组后的最后位置与运动方向。(a matlab code for second-order differential multi-agent flocking simulation, each agent s dynamics is described by using differential equation. it gives the figure of all agents position and velocities.)

this is very informative and knowledgeable.
