可以求出复杂网络中两节点间的距离以及平均路径长度，各节点的度及度的分布曲线，以及节点的聚类系数。(You can find out the distance and average path length between the two nodes in complex networks .you can also find out degree and degree distribution curve of each node, and the node clustering coefficient.)

这是一个关于稀疏高斯过程的matlab源码，可以用于计算测试输入的高斯预测值。( spgp_pred computes the SPGP predictive distribution for a set of test inputs. You need to supply a set of pseudo-inputs or basis vectors for the approximation, and suitable hyperparameters for the covariance. You can use any method you like for finding the pseudo-inputs , with the simplest obviously being a random subset of the data. It is coded for Gaussian covariance function, but you could very easily alter this. It is also fine to use for high dimensional data sets. spgp_lik is the SPGP (negative) marginal likelihood and gradients with respect to pseudo-inputs and hyperparameters. So you can use this if you wish to try to optimize the positioning of pseudo-inputs and find good hyperparameters, before using spgp_pred . I would recommend initializing the pseudo-inputs on a random subset of the data, and initializing the hyperparameters sensibly. Its current limitations are that 1) it is slow and memory intensive for high dimensional data sets 2) it is heavi)

说明：  完成KNN聚类，是一种比较基础的聚类算法，根据与邻居之间的距离判断(finish knn cluster,it is a basic function,you can use it to complish a cluster)

运用MATLAB工具箱实现图像处理的GUI程序设计 1）图像的读取和保存。 2）设计图形用户界面，让用户能够对图像进行任意的亮度和对比度变化调整，显示和对比变换前后的图像。 3）设计图形用户界面，让用户能够用鼠标选取图像感兴趣区域，显示和保存该选择区域。 4）编写程序通过最近邻插值和双线性插值等算法将用户所选取的图像区域进行放大和缩小整数倍的操作，并保存，比较几种插值的效果。 5）图像直方图统计和直方图均衡，要求显示直方图统计，比较直方图均衡后的效果。 6）能对图像加入各种噪声，并通过几种滤波算法实现去噪并显示结果。比较去噪效果。7）频谱处理，能够分析图像频谱，显示频谱图。 8）设计巴特沃斯低通滤波对图像进行低通滤波处理，显示结果。 9）设计高斯高通虑波器，显示结果。 (The realization of the use of MATLAB image processing toolbox GUI Programming)

研华的PCL733 PCL734程序库，直接调用控制板卡，很好用的啊(Advantech' s PCL733 PCL734 library, direct calls to control the board, very good use ah)

THIS IS THE MATLAB SOURCE CODE

通过 matlab 编程实现捷联惯导系统初始对准、惯导解算的全过程。 1）初始自对准：利用前10分钟实验车静止的数据进行惯导系统的自对准。采用前2分钟数据进行解析粗对准，后8分钟数据用五状态Kalman滤波器实现精对准；为了验证精对准性能，可在粗对准结果上把航向角人为加一定幅度（如10度）的误差，观察精对准的收敛性能。 2）纯惯导解算：对准结束后转入纯惯性导航解算，要求进行双子样的圆锥和划摇补偿，即每20ms完成一次导航解算，输出完整的导航结果包括三个姿态、两个水平速度和两个水平位置（天向通道发散不必输出），并给出姿态、速度、位置随时间的变化曲线以及位置误差曲线。(The whole process of initial alignment and inertial navigation solution of strapdown inertial navigation system is realized by matlab programming.)
