rk4_single_step(f, h, initial, time, parameters, inputs)

Performs a single step of the Runge-Kutta 4th order (RK4) method for solving ordinary differential equations.

Parameters: - f: callable

Function representing the ODE system. Should take (state, time, parameters, inputs) as arguments.

• h: float

  Step size for the RK4 method.

• initial: np.ndarray

  Initial state vector of the system.

• time: float

  Current time.

• parameters: tuple or dict

  Parameters needed for the ODE system.

• inputs: tuple or dict

  External inputs to the ODE system.

Returns: - np.ndarray

Updated state vector after a single RK4 step.
