Expand description

Re-exports Solve ODE using the Dormand-Prince method (RK45)

This is an adaptive step size method based on embedded Runge-Kutta formulas. It uses a 5th-order method with a 4th-order error estimate.

§Arguments

  • f - ODE function dy/dt = f(t, y)
  • t_span - Time span [t_start, t_end]
  • y0 - Initial condition
  • opts - Solver options

§Returns

The solution as an ODEResult or an error
