Newton interpolation formula. A form of writing the Lagrange interpolation formula by using divided differences : $$ \tag {1 } L _ {n} ( x) = \ f ( x _ {0} ) + ( x - x _ {0} ) f ( x _ {0} ; x _ {1} ) + \dots + $$. $$ + ( x - x _ {0} ) \dots ( x - x _ {n - 1 } ) f ( x _ {0} ; \dots ; x _ {n} ), $$.

Aug 13, 2019 · Interpolation is an estimation of a value within two known values in a sequence of values. Newton’s divided difference interpolation formula is a interpolation technique used when the interval difference is not same for all sequence of values. Suppose f (x 0 ), f (x 1 ), f (x 2 )………f (x n) be the (n+1) values of the function y=f (x) corresponding to the arguments x=x 0, x 1, x 2 …x n, where interval differences are not same.

Newton's Interpolation Formulae As stated earlier, interpolation is the process of approximating a given function, whose values are known at tabular points, by a suitable polynomial, of degree which takes the values at for Note that if the given data has errors, it will also be reflected in the polynomial so obtained.

Formula (1) is called Newton's interpolation formula for unequal differences. When the $ x _ {i} $ are equidistant, that is, if. $$ x _ {1} - x _ {0} = \dots = x _ {n} - x _ {n - 1 } = h, $$. then by introducing the notation $ ( x - x _ {0} )/h = t $ and expressing the divided differences $ f ( x _ {0} ; \dots ; x _ {k} ) $ in terms of the ...

As with other difference formulas, the degree of a Newton interpolating polynomial can be increased by adding more terms and points without discarding existing ones. Newton's form has the simplicity that the new points are always added at one end: Newton's forward formula can add new points to the right, and Newton's backward formula can add new points to the left. The accuracy of polynomial interpolation depends on how close the interpolated point is to the …

In the method of interpolation, it is assumed that the function is capable of being expressed as a polynomial. This assumption is based on Weierstrass approximation theorem. That is, the existence of an interpolating polynomial is supported by the theorem. P. Sam Johnson (NITK) Newton’s Interpolation Methods February 7, 2020 7/47
