NP

What is the complexity of cubic spline interpolation?

O(n)

NP

Def. Interpolation

Spezialfall der Approximation: die Werte der Funktion und der Interpolanten müssen an bestimmten Stellen gleich sein.

NP

What is the difference between approximation and interpolation?

Interpolation is a special case of approximation: If the function *f* and the approximant *p* have to be equal at certain points, the approximant becomes an interpolant.

NP

What is the advantage of the scheme of Aitken and Neville over the Lagrange polynomials?

The scheme of Aitken and Neville can evaluate *p(x) *at an intermediate point without an explicit formulation of *p.*

NP

Is the interpolant *p* that can be constructed using the scheme of Aitken and Neville identical to the sum of Lagrange polynomials for the same support points?

Yes, because of the uniqueness of the interpolation problem.

NP

Is polynomial interpolation with equidistant nodes a well-conditioned problem?

No, for large *n *(7 or 8 and up), polynomial interpolation with equidistant nodes is extremely ill-conditioned.
