KConstQ:

Path: SC/DemoFuns

% The constraint equations and Jacobians. 
 The outputs are

   Holonomic         Non Holonomic
   ---------         -------------
   phi               phi
   phiQ              A
   phiT              0
   phiDot            BDot
   phiQDot           ADot

 where the holonomic constraints are of the form

   phi(q,t) = 0

 and the non holonomic constraints are of the form

   A(q,t)qDot + B(q,t) = 0
