一个二维静电场，电位函数为φ（x, y），将正方形分成25个正方形网格。有16个内部网格点。假定16个网格点的初值都定为零，试用超松弛法确定16个内部网格点的电位值。(A two dimensional electrostatic field, the potential function for phi (x, y), the square into 25 square grid. There are 16 internal grid point. Assume that 16 mesh point of initial value at zero, trial overrelaxation method to determine the potential value of 16 internal grid point.)

在离散数据的基础上补插连续函数，使得这条连续曲线通过全部给定的离散数据点。插值是离散函数逼近的重要方法，利用它可通过函数在有限个点处的取值状况，估算出函数在其他点处的近似值。插值：用来填充图像变换时像素之间的空隙。(On the basis of discrete data, a continuous function is inserted to make the continuous curve pass through all the given discrete data points. Interpolation is an important method of approximation of discrete functions. It can be used to estimate the approximate values of functions at other points by means of the values of the functions at finite points. Interpolation: used to fill the space between pixels when an image is transformed.)

说明：  hough变换的最后一步，即通过找到的几个变换域中的几个点，确定原始空域中的直线！(hough transform the final step, that is, several transform domain by finding a few points to determine the air space in the original line!)
