ESAssignDraper:

---------------------------------------------------------------------------
   Apply eigenvector assignment.
   vD is entered with nan where you don't
   care about the value of the eigenvector.
---------------------------------------------------------------------------
   Form:
   f = ESAssignDraper( g, lambda, vD, r, fC )
---------------------------------------------------------------------------
