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.)

4种计算积分的方法，并对精度进行比较，梯形法则，simpson法则(4 methods for calculating integral)

偏最小二乘法中的交叉有效性计算,看看，可能有用(PLS cross-validity of the calculation, see, may be useful)

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.)
