Metodi Multistep con accelerazione per la risoluzione numerica dei sistemi di equazioni differenziali ordinarie

In this paper a procedure for the acceleration of the convergence is given. It allows the doubling of the order of the multistep methods for the numerical solution of the systems of ordinary differential equations: $$Y' = F(x,Y); Y_0 = Y(x_0 ) \begin{array}{*{20}c} x \\ {x_0 } \\ \end{array} \in a,b]$$ whereY andF(x,Y) aret-vectors.
