WebClassical Runge-Kutta method for dy/dt = f(t, y), y(t0) = y0, with step h, and the specified tolerance and max_steps. This function is a generator which can give infinitely many points: of the estimated solution, in pairs (t[n], y[n]). To get only finitely many values of: the solution we can for example do, >>> from itertools import islice ...

Web3. We also saw earlier that the classical second-order Runge-Kutta method can be interpreted as a predictor-corrector method where Euler’s method is used as the predictor for the (implicit) trapezoidal rule. We obtain general explicit second-order Runge-Kutta methods by assuming y(t+h) = y(t)+h h b 1k˜ 1 +b 2k˜ 2 i +O(h3) (45) with k˜ 1 ...
