Lagrange’s interpolation polynomial is used for the determination of the function on the basis of the given points. In point of fact, the indicator takes the coordinates of the points located between extern int begin and extern int end (marked with the red and blue lines on the chart), and calculates the coordinates of the next points using the Lagrange’s interpolation polynomial.
