epoch
Description:	The epoch at which to evaluate the RotatingLibrationPoint object.

Type:

Matrix of number (size = 3 x 3)

A 3x3 matrix containing the direction cosine matrix of the RotatingLibrationPoint system with respect to the ICRF.

myMatrix1 = myRotatingLibrationPoint1.GetDCMAtEpoch(myTimeSpan1);
