fft

3D流场计算，程序简单非常容易看懂。适合初学者学习(3D flow field)

主要用于三次样条拟合，对离散点进行拟合插值，(Three order spline fitting)

一些简单的UDF文件，实现流场中梯度和某一点压力的检测提取(Some UDF profiles)

时间序列预测算法。支持5种常见的算法 移动平均 非线性回归 指数平滑等(ar, ardemo ma)

主要用来计算抛物型偏微分方程的数值解，而且通过调用边界函数来计算方程，采用差分编程方式(Mainly used to calculate the parabolic partial differential equations numerical solution, and by calling the function to calculate the equation of the border, using differential programmatically)

多项式拟合，最小二乘法，c++版本实现，运行环境vc6(Polynomial fitting)

这是利用C++ 编的fft(This is the C series fft)

说明：  大名鼎鼎的burges 方程的Fortran语言程序。Burges方程式源项为零的NS方程，在某些情况下市很有用的。(Famous burges equation Fortran language program. Burges equation source term to zero NS equations, in some cases, city, very useful.)

迭代最小二乘法,反演中应用极广泛，非常经典(Iterative least-squares method，An extremely wide range of inversion, very classic)

根据传输线理论，计算无耗传输线的输入输出阻抗，画图表示电压电流和阻抗随线路长的变化(Based on transmission line theory to calculate the input and output impedance of the lossless transmission line, drawing, said the change of voltage, current and impedance with the line length)
