Purpose
To ask for user's confirmation of the system order found by SLICOT Library routine IB01OD. This routine may be modified, but its interface must be preserved.Specification
      SUBROUTINE IB01OY( NS, NMAX, N, SV, INFO )
C     .. Scalar Arguments ..
      INTEGER            INFO, N, NMAX, NS
C     .. Array Arguments ..
      DOUBLE PRECISION   SV( * )
Arguments
Input/Output Parameters
  NS      (input) INTEGER
          The number of singular values.  NS > 0.
  NMAX    (input) INTEGER
          The maximum value of the system order.  0 <= NMAX <= NS.
  N       (input/output) INTEGER
          On entry, the estimate of the system order computed by
          IB01OD routine.  0 <= N <= NS.
          On exit, the user's estimate of the system order, which
          could be identical with the input value of  N.
          Note that the output value of  N  should be less than
          or equal to  NMAX.
  SV      (input) DOUBLE PRECISION array, dimension ( NS )
          The singular values, in descending order, used for
          determining the system order.
Error Indicator
  INFO    INTEGER
          = 0:  successful exit;
          < 0:  if INFO = -i, the i-th argument had an illegal
                value.
