Lagrange Interpolation Lagrange interpolation is a well known, classical technique for interpolation [].It is also called Waring-Lagrange interpolation, since Waring actually published it 16 years before Lagrange [312, p. 323].More generically, the term polynomial interpolation normally refers to Lagrange interpolation. In the first-order case, it reduces to linear interpolation.

interpolation points are close together. In Lagrange interpolation, the matrix Ais simply the identity matrix, by virtue of the fact that the interpolating polynomial is written in the form p n(x) = Xn j=0 y jL n;j(x); where the polynomials fL n;jgn j=0 have the property that L n;j(x i) = ˆ 1 if i= j 0 if i6= j: The polynomials fL

these methods include (but are not limited to) • newton’s divided difference approach • the method of lagrange polynomials • regression analysis (linear and non-linear) • slisplines here we focus on lagrange interpolating polynomials because the method leads directly to the formulation of shape functions for higher order elements with an …
