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)

自己编写的求可达矩阵，层次划分 代码.使用时，替换已有矩阵，即可运算！ (I have written for reachability matrix, the level of classified code. Use, replace the existing matrix, computing can be!)

说明：  用Doolittle式的LU分解来求解线性方程组。(Solve the linear equations using Doolittle LU Decomposition!)

模拟Chaboche非线性随动硬化各向异性塑性的例子 -HILL和CHAB的实例(Chaboche simulation examples of anisotropic nonlinear kinematic hardening plastic -HILL and examples of CHAB)

abaqus粘弹性人工边界，手动添加比较简单的模型(learning abaqus)

Galileo单频定位程序，能基于rinex文件实现高精度定位，供编写时参考(Galileo single-frequency positioning program can achieve high-precision positioning based on RINEX file for reference when writing.)

网上看到很多关于矩阵求逆运算的代码，都很杂很乱，我把代码重新真理了一边，可以直接编译运行(See a lot of online matrix inversion code, very complex mess, I put the code back to the side of truth, you can directly compile and run)

一元稀疏多项式编程，希望对大家的编程有点用，欢迎下载(hope it useful to you)

本例是研究断裂问题的ABAQUS 子程序代码，使用Fortran语言编辑，研究扩展有限元的同志们可以借鉴一下。(This example is the study of fracture problems ABAQUS subroutine code, Fortran language editing, extended finite element study comrades can learn it.)
