Newton's divided difference polynomial matlab
WitrynaNewton’s polynomial interpolation is another popular way to fit exactly for a set of data points. The general form of the an n − 1 order Newton’s polynomial that goes through n points is: f(x) = a0 + a1(x − x0) + a2(x − x0)(x − x1) + ⋯ + an(x − x0)(x − x1)…(x − xn) which can be re-written as: f(x) = n ∑ i = 0aini(x ...
