  NSMP    (input) INTEGER
          The number of input and output samples, t.  NSMP &gt;= 0, and
          NSMP &gt;= 2*(M+L+1)*NOBR - 1, if INIT = 'L' or 'B'.

  N       (input/output) INTEGER
          The order of the linear part.
          If INIT = 'L' or 'B', and N &lt; 0 on entry, the order is
          assumed unknown and it will be found by the routine.
          Otherwise, the input value will be used. If INIT = 'S
