极坐标系下的画图及其转换公式，特殊作图需要用到(Polar coordinates of the drawing and the conversion formula, need to use special drawing)

三维目标下用扩展卡尔曼滤波对非线性系统的目标进行跟踪(By three-dimensional object using the extended Kalman filter for target tracking nonlinear systems)

局部Log.Euclidean协方差矩阵描述子 L2ECM SPD矩阵的空间并不是一个向量空间,而是一个黎曼流形。因此,传统 欧氏空间内的运算 例如欧氏距离、均值( Local Log-Euclidean Covariance Matrix (L2ECM) to represent neighboring image properties by capturing cor- relation of various image )

光在散射介质中的传播，输入光子步数和吸收系数，输出光子的轨迹(A 3-D Monte Carlo Simulation of a photon propagating in scattering and absorbing media. Given an input of the number of steps (iterations) for the photon to take and the absorption coefficient of media, this function calculates a random walk and returns coordinates of final position and total final distance origin.)

多变量微分方程的PID控制程序，通过调整一个参数使得六个变量都的到控制(PID control procedures for multi-variable differential equations, by controlling a parameter makes the six variables are to control)
