test
- 常见的几种密度分布函数的使用，适合新手学习。(The use of several probability density distribution functions. Suitable for novice.)
Desktop
- 三种方法计算计算Hurst指数（R/S）(Calculation and calculation of Hurst index (R/S) by three methods)
power_spectrum_density

Lagrange
- 拉格朗日数值计算方法，用matlab编写的数值计算方法中的拉格朗日拟合(Lagrangian numerical method)
pyVMD_any
- 变分模态分解的python版本，个人根据MATLAB版本译制而成(Python version of variational mode decomposition)
线性方程组计算
- 利用高斯消元法法求解病态矩阵——hilbert 矩阵的线性方程组。通过条件数分析，找出误差较大的原因。再利用 Jacobi 迭代方法、G-S 迭代方法和 SOR 迭代法做了进一步探究。另外，作为要求之外的，还使用共轭梯度法来求解方程以来进行对比，并利用Tikhonov 正则化的方法改善矩阵的条件数，来减小误差。(The Gauss elimination method is used to solve the linear equations of the ill conditioned mat
