lagrange algorithm experimental subject: Lagrange interpolation polynomial-related knowledge: through n+1 the number of nodes n of not more than the Lagrange interpolation polynomial as follows: one, Lagrange interpolation basis function, k = 0,1, ..., n. In addition, the added C language drawn graphics are as follows 1. Screen coordinate system coordinates of the origin of the upper-left corner of the screen, x-axis level of the right, y-axis vertically downward. 2. Mapping function commonly used Newton algorithm
