针对由于抖动和环境干扰造成的拍摄影像模糊问题，利用维纳滤波法进行图像恢复(As for the environmental disturbance caused by jitter and image blur shooting problems, the use of Wiener filtering method for image restoration)

对k近邻方法进行改进，knn方法中自动获取k值(Automatic selection of K value in KNN algorithm)

用于潮汐模拟计算；能计算相关模型；包括两部分：1是用户界面编程2是预测潮汐等(TMD (Tide Model Driver)TMD is a Matlab package for accessing the harmonic constituents for the ESR/OSU family of high-latitude tide models, and for making predictions of tide height and currents. TMD includes two components: (1) a graphical user interface (GUI) for quickly browsing tide fields, zooming in on regions of interest, and selecting points and time ranges for predictions of specific variables and (2) a set of scripts for accessing tide fields and making predictions. Each component is described below.)

采用smith预估计对pid控制进行优化，可以达到很好的控制效果哦(Estimated using pre-smith optimized for pid control, can achieve good control effect oh)

matlab程序，fft方面的，可以用来学习下，谢谢(programme of fft on matlab)

说明：  卷积编码程序。用matlab编写，希望对大家有用。(Convolutional coding and decoding process. Prepared using matlab, we want to be useful.)

随机采样文件1，在MATLAB上进行仿真的(random sample)

实验一：三次样条插值（P56，例6） 一、实验目的： 1) 掌握三次样条插值的运用 2) 了解拉格朗日插值在高次上的误差 二、实验环境：Matlab6.5 三、实验内容： 1) 给定函数f(x)=1/(1+x2)，-5<=x<=5，节点xk=-5+k，(k=0,1,2…10)，用三次样条插值求S10(x)，S10’(-5)=f’(-5)，S10’(5)=f’(5)。 2）作原函数f(x)，拉格朗日插值函数Ln(x)，三次样条差值函数Sn(x)。画出三个函数的图像，比较它们的区别。 (Experiment I: cubic spline interpolation (P56, cases of 6) First, the experiment was: 1) cubic spline interpolation to master the use of 2) understanding of Lagrange interpolation in high-error second, experimental environment: Matlab6 .5 c, experimental elements: 1) a given function f (x) = 1/(1+ x2),-5 <= x <= 5, node xk =- 5+ k, (k = 0,1,2 ... 10), using cubic spline interpolation for S10 (x), S10 (-5) = f (-5), S10 (5) = f (5). 2) for the original function f (x), the Lagrange interpolation function Ln (x), cubic spline difference function Sn (x). Draw the three functions of images, compare the difference between them.)
