自己遍的牛顿迭代法求解二元二次方程的程序 迭代步数可以自己设定-Their times of Newton iteration procedure for solving the dual quadratic equation iteration step can be set for

3D盒子模型动画，html5 3D立方体动画，演示了各个方向的翻转动画，点击下边各个方向按钮，盒子会在对应方向上翻转，鼠标移上盒子，动画效果即可播放。

通过计算方差，确定划分坐标轴，最后，将点云划分到一个个格子中，这样的好处在于可以将噪点和有效点分别存储于不同的格子中，方便进行去噪。(k-d tree create;By calculating the variance, the coordinate axis is determined. Finally, the point cloud is divided into a number of lattices. The advantage is that the noise and the effective points can be stored in the different lattice, so that the noise can be de-noised conveniently.)

说明：  时域提取方法，可用于滚动轴承，齿轮等振动信号的提取(The time domain method can be used to extract vibration signals of rolling bearings and gears)

更新版本的凸优化工具箱，里面有安装方法和具体实例(Updated version of the convex optimization toolbox, which has installation methods and concrete examples)

语音信号通过滤波器分析，matlab程序编写-voice signal through the filter, Matlab programming

说明：  matlab实现全息成像！！！！！！！！！！(Holographic imaging based on MATLAB)

对数据进行分段fft分析，最后进行平均，功能类似FFT的平滑处理。(The data are analyzed by segmented fft and eventually averaged. The function is similar to that of FFT smoothing.)

GPS/IMU融合之后产生融合之后的轨迹(Trajectory after GPS/IMU fusion)

一款超炫酷CSS3鼠标悬停动画特效。该特效中，通过CSS圆形渐变来制作圆点(A super cool CSS3 mouse hover animation special effects. In this effect, circle hovering is made by CSS circle gradient.)
