T - the type of the field elementspublic class GillFieldIntegrator<T extends RealFieldElement<T>> extends RungeKuttaFieldIntegrator<T>
This method is an explicit Runge-Kutta method, its Butcher-array is the following one :
    0  |    0        0       0      0
   1/2 |   1/2       0       0      0
   1/2 | (q-1)/2  (2-q)/2    0      0
    1  |    0       -q/2  (2+q)/2   0
       |-------------------------------
       |   1/6    (2-q)/6 (2+q)/6  1/6
