Class FieldCjSjCoefficient<T extends CalculusFieldElement<T>>

java.lang.Object
org.orekit.propagation.semianalytical.dsst.utilities.FieldCjSjCoefficient<T>
Type Parameters:
T - type of the field elements
public class FieldCjSjCoefficient<T extends CalculusFieldElement<T>> extends Object
Compute the Sj(k, h) and the Cj(k, h) series and their partial derivatives with respect to k and h.

Those series are given in Danielson paper by expression 2.5.3-(5):

Cj(k, h) + i Sj(k, h) = (k+ih)j

The Cj(k, h) and the Sj(k, h) elements are store as an ArrayList of Complex number, the Cj(k, h) being represented by the real and the Sj(k, h) by the imaginary part.
