Jacobi矩阵一般是坐标变换时用的——这个坐标系的坐标依次对那个坐标系的坐标求偏导数即得Jacobi矩阵。积分时从直角坐标变到球坐标、极坐标肯定要在积分号里乘上Jacobi矩阵的行列式。 若其特征值全为正，则此Jacobi矩阵正定，即它的任何二次型都大于零。并且如果是对称Jacobi矩阵，还可以实相合于一个单位阵。是比较强的条件。矩阵A的特征值是这个关于x的方程的所有根 det(A-xI)=0(Jacobi)

学习现代控制理论的经典教材 结合matlab 之前 一定要好好看看(Study of modern control theory of the classic textbook binding matlab before must be good to have a look)

轮轨接触点扫描方法，用扫描的方法计算求得任意轮轨型面的轮轨接触点(Wheel-rail contact point scanning method, the method of calculation obtained by scanning any type of wheel and rail wheel-rail contact point surface)

说明：  降低数据维度，提取高级特征，使得用较少的特征来表示最后的结果(Reduce the data dimension, extract high-level features, so that fewer features are used to represent the final result)

说明：  用于函数逼近的径向基逼近和差值，是一个基础函数，包括高斯及二项式两种，可拓展到多个应用领域(Radial basis functions are use for function approximation and interpolation. This package supports two popular classes of rbf: Gaussian and Polyharmonic Splines (of which the Thin Plate Spline is a subclass). The package also calculates line integrals between two points.)
