Newton Interpolation Method Values yi of the interpolating polynomial at the points xi. Coordinates of the points of interpolation are stored in vectors x and y. Horner s method is used to evaluate a polynomial. Second output parameter a holds coeeficients of the interpolating polynomial in Newton s form.
