faa.tg.aircraft.integrator
Class EulerIntegrator<E extends StateVector<E>>

java.lang.Object
  faa.tg.aircraft.integrator.FixedStepIntegrator<E>
      faa.tg.aircraft.integrator.EulerIntegrator<E>

All Implemented Interfaces:

Integrator<E>

public class EulerIntegrator<E extends StateVector<E>>
extends FixedStepIntegrator<E>

 Euler integration is fixed time-step first order integration. So for some
 function f, where the i and i+1 states are a and b respectively and t is 
 the timestep, f(b) = f(a) + f_dot(a)*t. This method is very unstable and is
 unsuitable most cases.
