Detailed Description

Numerical method that generates temporal extrapolation of the data with Lagrangian polynoms.

The method computes Lagrange polinomial extrapolation of order \(k\) in time. factor defines extrapolation length:

\[ u(t+dt*factor) = \sum_{i=0}^n y_i l_i \]

where

\[ l_i(x) = \prod_{j=0, j\neq i}^k \frac{x-x_j}{x_i-x_j}\]

The first avalible point has \( t_0 = -k$. The last avalible point has \) t_k = 0$.
