% Create an estimator from a state space system.
 Create an estimator based on the state equations
   .
   x = ax + bw
   y = cx + v

   E(ww') = q
   E(vv') = r
   E(vw') = n

   The estimator will be of the form

   xE = a*xE + b*u + k*(y-c*xE)

--------------------------------------------------------------------------
   Form:
   [k, sInf] = QCE( a, c, q, r, b, n )
