Abstract
The system of four differential equations in the external invariant satisfied by the four master integrals of the general massive 2-loop sunrise self-mass diagram is solved by the Runge–Kutta method in the complex plane. The method offers a reliable and robust approach to the direct and precise numerical evaluation of Feynman graph integrals.
