Expand description
Runge-Kutta-Fehlberg 4/5th order integrator.
This integrator uses the Runge-Kutta-Fehlberg method, which is an adaptive step size integrator. It calculates six intermediate values (k1, k2, k3, k4, k5, k6) to estimate the next step solution and the error. The step size is automatically adjusted based on the estimated error to maintain the desired tolerance.
§Member variables
tol
: The tolerance for the estimated error.safety_factor
: The safety factor for the step size adjustment.min_step_size
: The minimum step size.max_step_size
: The maximum step size.max_step_iter
: The maximum number of iterations per step.
