Mathematica实现数值分析

包括基本的克里金(Kriging)插值法实现代码，仅实现基本方法部分，不包含扩展克里金方法( kriging uses ordinary kriging to interpolate a variable z measured at locations with the coordinates x and y at unsampled locations xi, yi. The function requires the variable vstruct that contains all necessary information on the variogram. vstruct is the forth output argument of the function variogramfit. This is a rudimentary, but easy to use function to perform a simple kriging interpolation. I call it rudimentary since it always includes ALL observations to estimate values at unsampled locations. This may not be necessary when sample locations are not within the autocorrelation range but would require something like a k nearest neighbor search algorithm or something similar. Thus, the algorithms works best for relatively small numbers of observations (100-500). For larger numbers of observations I recommend the use of GSTAT. Note that kriging fails if there are two or more observa)

converts a binary undirected adjacency graph into a hypergraph. The output is a non symmetric matrix where the columns are the vertices and the rows are the hyper edges.

一个用拟牛顿算法求解优化问题的程序，此程序为MATLAB程序，大家用前自己注意检查一下(A Quasi-Newton algorithm using optimization procedures, the procedures for the MATLAB program, we pay attention to before their own check)

说明：  文件中有大量 数据样本，根据样本进行数据处理，求均值，插值，最大值，最小值等(There are a large number of data samples in the file. According to the samples, data processing is carried out to find the mean value, interpolation, maximum value, minimum value, etc)

有限元方法和计算流体力学的经典教材，内容很不错(Finite Element Method- Fluid Dynamics- Zienkwicz and Taylor)

Delphi实现最小二乘法，进行多点拟合，目前支持4点拟合(Delphi realizes the least square method and multi-point fitting. At present, it supports four-point fitting.)

使用matlab进行 有限元计算，内含多种方式方法，欢迎交流讨论(Finite element calculation using matlab)

在轨迹给定长度范围内，各个waypoint给定确定的速度范围约束，规划处平滑的速度变化曲线(Within the given length range of the trajectory, each waypoint is given a determined velocity range constraint and a smooth velocity variation curve at the planning point)
