CollProbSet:

--------------------------------------------------------------------------
  Calculates the probability of collision given two ellipsoid sets. For
  a single ellipsoid relative to the origin, pass in empty matrices for 
  the second set of inputs. The inputs should have consistent units,
  i.e. either m or km.

   Since version 7.
--------------------------------------------------------------------------
  Form: 
  [P] = CollProbSet( P0,S1,xc1,S2,xc2,Ssc, n );
  [P] = CollProbSet( P0,S1,xc1,[],[] ,Ssc, n );
--------------------------------------------------------------------------

  Inputs: 
  -------
  P0          (1)   Ellipsoid probability level, i.e. 1 for one sigma
  S1, S2     (3,3)  Ellipsoid definitions
  xc1, xc2   (3,1)  Centers of ellipsoids
  Ssc        (3,3)  Definition of hard-body spacecraft (spherical)
  n           (1)   Number of scaled ellipses to use

  Outputs:
  --------
  P          (1)    Probability of collision
