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 …
Abstract Two new Runge–Kutta (RK) pairs of orders 6 (4) and 7 (5) are presented for solving numerically the inhomogeneous linear initial value problems with constant coefficients …
