有限元热计算的算例，做有限元热分析的朋友比较有用(Finite element calculation of hot example, to do finite element analysis of hot Friend more useful)

模型大小延伸程序；及实现快速傅里叶变换的小程序。该两程序通俗易懂，适合初学者(Model extension、 FFT)

说明：  Kim 的非线性有限元分析经典教材，教材很经典，对于静态有限元分析讲的很透彻，书中附有matlab代码(Kim's nonlinear finite element analysis classic textbook, the textbook is very classic, for static finite element analysis is very thorough, the book with matlab code)

实现复数运算符的重载，对C++初学者来说有一定的参考价值。(Complex operator overloading, C++ beginners a certain reference value . )

计算声发射时域信号特征值：裕值，振幅因子FK、fc，峭度，(Calculation of acoustic emission time-domain signal characteristic values: margin value, the amplitude factor FK, fc, kurtosis,)

此程序为基于时域有限差分法的matlab程序，主要是计算二维MUR吸收方柱散射(This procedure is based on finite difference time domain method matlab program, mainly of two-dimensional scattering MUR absorbing square columns)

这是一个用FDTD算法计算二维导体方柱散射场RCS的matlab程序.采用UPML吸收边界条件和高斯脉冲源激励,对于学习FDTD方法中的激励源加入,近-远场外推,吸收边界设置等很有帮助(This is a FDTD algorithm using two-dimensional square cylinder conductor scattering RCS of the matlab program. UPML absorbing boundary conditions used and the Gaussian pulse source excitation, the FDTD method to study the excitation source join, near- far outside the push, absorbing boundary settings, such as helpful)

小波包分析提取振动信号中的特征频率，调试通过可以使用，自己编的5种调制信号。( Wavelet packet analysis to extract vibration signal characteristic frequency, Debugging can be used, Own five modulation signal.)

采用时域数值仿真算法较为精确的仿真铣削加工过程动态力(By using numerical simulation algorithm is more accurate simulation of milling process dynamic force)

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)
