说明：  用em算法估计高斯混合模型参数，matlab代码(Estimation of Gaussian mixture model parameters by EM algorithm)

分享一个外国人编写的FDTD程序,可以用来计算微带线和微带贴片天线,程序中采用的是均匀网格划分,但也可以在容易地在它基础上改写成非均匀网格.其边界条件与Sheen的程序不同,这里采用二阶技术.(Prepared to share a foreigner FDTD procedures, can be used to calculate the microstrip lines and microstrip patch antenna, the procedure used is uniform mesh, but can also easily rewrite it into the basis of non-uniform grid. its boundary conditions with different processes and Sheen, where second-order technology.)

说明：  计算混沌系统的lyapunov指数和poincare截面(Calculation of chaotic systems lyapunov index and cross-section poincare)

程序是庄茁大神经典的Johnson-Cook模型隐式算法 另外包括一个 ABAQUS-Standard用户材料子程序实例的文档说明(The program is a classic Johnson-Cook model implicit algorithm and it includes documentation of an ABAQUS-Standard user material subroutine example)

fluent 旋转边界算例，可以了解运动机械在fluent模拟中的设置(fluent rotation the boundary example, you can understand the mechanical movement set in fluent simulation)

基于模式耦合方法建立三维面波传播模型，该代码对于做波场模拟的同学很有用。(This program calculates the wavefield produced by a monochromatic surface wave mode incoming on a 3D cartesian structure. It is based on mode coupling and multiple scattering.)

说明：  研究舍入误差的例程，可以帮助初学计算方法的人。(Of rounding error in the routine that can help beginners who calculation.)

代数涡粘模型用于计算近壁湍流的速度场，1D 4阶RK 积分(Algebraic eddy viscosity model is used to calculate the near-wall turbulence velocity field, 1D 4-order RK integration)

数字信号处理FFT算法rfft.c，简单易懂。。(Digital signal processing FFT algorithm rfft,Straightforward..)
