把matlab计算后的数据保存成obj格式的文件，能保存点和点点之间的连接关系，即obj格式的中的v和f(Obj format to save data into files that can save the points and little connection between the relationship that the v in obj format and f)

说明：  通过坐标轴，随即显示坐标轴上的值域及坐标的位置（x,y轴的位置）。(rand number show)

wavelab预编译文件，能加速wavelab的运行，给那些matlab不能编译m文件的用户准备的。(wavelab pre-compiled documents can be accelerated wavelab of operation, Matlab not to those documents compiled m users of.)

稀疏分解图像重建程序，把图像分解成多个小块图像，然后再各个子块重建后边缘处理后合并成整个图像。(sparse decomposition image reconstruction process, the image is divided into a number of small images, then each sub-block redevelopment edge after the merger into the whole image.)

this code optimize the parameter of PID controller

数字滤波器是一种用来过滤时间离散信号的数字系统，通过对抽样数据进行数学处理来达到频域滤波的目的。(FIR Digital Filter Design)

The OcamCalib Toolbox for Matlab allows the user (also inexpert users) to calibrate any central omnidirectional camera, that is, any panoramic camera having a single effective viewpoint.

svm工具箱，可以很好进行分类，并附有实例，可以很直接的看出分类效果(svm toolbox, well classification, with examples, can direct that the classification results)

阐述了LMS算法中步长选择对结果收敛的影响(Described step LMS algorithm convergence results)

说明：  简单实现了基于项目的协同过滤代码，MATLAB实现，需要解压(Simple implementation of project-based collaborative filtering code)
