Detailed Description
template<typename T>
class til::Lagrange4Interpolation< T >
Interpolation using Lagrange polynomials of order 4.
Computes the Lagrange interpolation of the sequence (f1, f2, f3, f4) (supposed to be equally spaced and at position (-1, 0, 1, 2)). 'x' is the position of the point where we want an interpolated value, and has to be in the range [0, 1]. The Lagrange polynomial is the only third order polynomial fitting all four points.
