DS证据理论的matlab实现，是数据挖掘的重要理论，可实现故障诊断。(Matlab implementation of DS evidence theory, data mining is an important theory, fault diagnosis can be achieved.)

说明：  主要用于Fluent 中风剖面、湍流剖面以及耗散率剖面的开发，应用的是日本的规范。(It is mainly used for the development of fluent stroke profile, turbulence profile and dissipation rate profile, and it is applied to the specifications of Japan.)

采用M语言仿真stribeck的三轴伺服系统，可以在低速情况下观察较强的摩擦现象(With M-language simulation stribeck three-axis servo systems, in the case of low friction phenomena observed strong)

速度曲线规划，在给定长度path 曲线上，根据各waypoint的速度约束，规划出平滑的速度曲线(speed curve planning.In a given length path curve, according to the speed of the waypoint constraints, planning a smooth speed curve.)

用多重网格方法求解泊松方程，偏微分方程求解(use multigrid method to solve poisson equation, pde solver)

说明：  PRP共轭梯度法优化计算，采用FORTRAN语言(PRP conjugate gradient method optimization, the use of FORTRAN language)

矩阵排序，按照行排序。 例如 矩阵[ 1 2 3 4 5 4 1 3 2 1 3 5 6 9 7]排序后为： [ 1 2 3 4 5 3 5 6 9 7 4 1 3 2 1] (matrix row sort )

截断奇异值分解技术是一种正则化方法，用于不适定问题的数值计算(Truncated Singular Value Decomposition is a regularizaiton method for ill-conditioned problem computation.)

使用matlab编写的时域有限差分法，pec边界的光子晶体。(Written using matlab finite difference time domain method, pec boundary of the photonic crystal.)
