Interpolation algorithms: interpolation methods include: (1) linear interpolation (2) parabolic interpolation (3) Lagrange interpolation. The three methods use the discrete data to approximately simulate the curve function trend, and then give the function values corresponding to the designated discrete points. Different interpolation functions are used, and the effect of approximation is different. Linear interpolation needs to give three points according to the given two points, and the general form is solved by Lagrange interpolation
