系统仿真导论第一个实验程序，龙格库塔实验程序(Introduction The first experimental system simulation program, Runge-Kutta experimental procedures)

说明：  用LBM代码编写的由于温差而产生的自然对流小程序(As with the LBM code written in natural convection resulting from temperature applet)

同时辨识模型阶次及参数算法。用阶次递推算法，结合AIC法——利用赤池信息准则辨识上例的模型阶次和参数。(At the same time identify model order and parameters algorithm. By order recursive algorithm, combined with AIC method- the use of Akaike information criterion to identify the cases of the model order and parameters.)

常微分方程数值解法，又是一个数值分析的常用算法(Numerical Solution of ordinary differential equations, numerical analysis is a common algorithm)

三维PML-FDTD的C语言代码，完全匹配层的C语言实现(3D PML-FDTD in the C language code, perfectly matched layer in C language)

样条插值算法的matlab代码，包括一次样条插值，二次样条插值和三次样条插值，可根据需要选择(Spline interpolation algorithm matlab code, including a spline interpolation, quadratic spline interpolation and cubic spline interpolation, can be selected)

随机数生成程序，该随机数呈zipf分布，就是大家常说对于内容的访问遵循80/20原则，也就是20 的内容，会占有80 的访问量。(Random number generator, the zipf was distributed random numbers, that is, we often say that the access to the content to follow the 80/20 principle, which is 20 of the content will occupy 80 of visits.)

FFT快速傅里叶变换 采用基4 fft实现的c语言版(FFT Fast Fourier Transform implemented using the base 4 fft c language version)

牛顿法计算方程，能计算非线性方程/方程程组，有需要的能试试，主要是数学方法的实现 (Newton method to calculate the equation to calculate the nonlinear equation/equation of equations, needs to try, mainly the implementation of the mathematical methods)

C 语言，模拟流体相平衡过程，得到混合气体平衡态以后的工况参数(C language to simulate fluid phase equilibrium process, to obtain a mixed gas equilibrium after working parameters)
