Fitted modifications of classical Runge‐Kutta pairs of orders 5(4)
Fitted modifications of classical Runge‐Kutta pairs of orders 5(4)
Runge‐Kutta pairs sharing orders 5 and 4 are among the most celebrated methods for solving initial value problems. Here, after considering the phase lag as a function of frequency v , we derive a modification of a particular pair. Namely, we present a zero dissipative pair with vanished phase error …
