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)

一些有用的fem用来matlab进行有限元分析编程的源代码(Some useful fem used to matlab for finite element analysis of programming source code)

这是用于将格点数据转化站点数据的fortran程序，比较详细，可以画图(This is a fortran program for the grid data into the site data in more detail, you can draw)

Echo cancellation using NLMS adaptive filter

求给定矩阵的逆矩阵和行列式值。已经经过测试，与matlab做了对比，计算结果可靠(Seeking a given matrix inverse matrix and determinant value. Has been tested with Matlab contrast, reliable calculation results)

空间计量经济学常用的casetti_models、far_models、gmm_models、gwr_models、sac_models、sar_models等多种模型源代码(Multiple models of the used spatial econometrics casetti_models, far_models gmm_models gwr_models sac_models sar_models source code)

用于处理信号，对信号进行小波包分解，此处进行了三层分解计算，可以进行迭代。(Used to process the signal, the wavelet packet decomposition of the signal, where the three-tier decomposition of the calculation can be iterated.)

ADINA 系统是一个单机系统的程序，用于进行固体、结构、流体以及结构相互作用的流体流动的复杂有限元分析。借助 ADINA 系统，用户无需使用一套有限元程序进行线性动态与静态的结构分析，而用另外的程序进行非线性结构分析，再用其他基于流量的有限元程序进行流体流动分析。此外， ADINA 系统还是最主要的、用于结构相互作用的流体流动的完全耦合分析程序（多物理场）。(ADINA System is a stand-alone system program for performing complex fluid flow finite element solid structure, and fluid structure interaction analysis. With ADINA system, users do not need to use a finite element program linear static and dynamic structural analysis, but with additional nonlinear structural analysis program, and then the other program flow based on finite element analysis of fluid flow. In addition, ADINA system or main, fully coupled analysis program for fluid flow structure interaction (multi-physics).)

本书介绍了XFEm在结构件的断裂分析中的应用(this book introduces the application of XFEM in the field of fracture analysis)
