ransac直线拟合：使用ransac方法剔除不好的点，留下好的点做直线拟合，这样拟合出的直线更符合实际，因为没有了错误数据的参与。(ransac linear fitting: Use ransac methods eliminate the bad points, making a good point to make fitting a straight line, so that the fitted straight line is more realistic, because there is no involvement of erroneous data.)

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

以随机的中弱大气湍流为背景，可用于计算大气湍流下准直高斯光束的光强分布，光束扩展以及光束角漂移(The random weak atmospheric turbulence as the background can be used to calculate atmospheric turbulence of collimated Gaussian beam intensity distribution and beam propagation and beam angle drift)

C语言矩阵求逆模块,输入矩阵调用此模块即可求出对应的逆矩阵(C language matrix inversion module)

C语言实现Matlab中interp1和interp2中的功能。(Interp1 and interp2 in Matlab, C language the function.)

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.)
