  JOBU    CHARACTER*1
          Indicates whether the user wishes to accumulate in a
          matrix U the unitary state-space transformations for
          reducing the system, as follows:
          = 'N':  Do not form U;
          = 'I':  U is initialized to the unit matrix and the
                  unitary transformation matrix U is returned;
