二维涡流位置及流场分布计算程序，Vortex Panel Method (Two-dimensional eddy current distribution of the location and flow field calculation program, Vortex Panel Method)

自己总结的一些现阶段用得比较多的尾流计算模型(Some of your summary of present with more drafting calculation model)

说明：  FFT（Fast Fourier Transformation）是离散傅氏变换（DFT）的快速算法 [1] 。即为快速傅氏变换。它是根据离散傅氏变换的奇、偶、虚、实等特性，对离散傅立叶变换的算法进行改进获得的。(FFT (Fast Fourier Transform) is a fast algorithm of discrete Fourier Transform (DFT). That is fast Fourier transform. According to the odd, even, imaginary and real characteristics of discrete Fourier transform, the algorithm of discrete Fourier transform is improved.)

三维数据点拟合空间球体的算法，利用最小二乘法实现空间球的拟合。(3D data points fitting the space sphere algorithm using the method of least squares fitting space ball.)

计算声子晶体固-液和固-气体系，和实验测试吻合，很适应(Suitable for computing phononic crystal solid-liquid and solid and gas, and experimental agreement )

APRIORI ALGORITHM IMPLEMENTATION

近似熵和互近似熵的matlab代码，用于脑波分析很有用(Approximate entropy and cross approximate entropy matlab code for brain wave analysis useful)

二阶精度的FDTD正演算法，可用于井间电磁波探测模拟(The accuracy of the second order FDTD are algorithm Can be used to detect simulation between Wells electromagnetic waves )

21位水仙花数的寻找，里面用到了大数乘法等细节上的东西。(find the 21 digits narcissus.)

说明：  一维黎曼问题，一维问题，即激波管问题，是一个典型的一维可压缩无黏气体动力学问题，并有 解析解。对它采用二阶精度两步差分格式进行数值求解。(Riemann problem, One dimensional problem, the shock tube problem, is a typical one-dimensional compressible non viscous gas dynamic problem with analytic solutions. It is solved numerically by two order two step difference scheme.)
