NAME
       cgssco - General sparse solver condition number estimate.

SYNOPSIS
        SUBROUTINE CGSSCO ( COND, HANDLE, IER )

        INTEGER           IER
        REAL              COND
        DOUBLE PRECISION  HANDLE(150)


PURPOSE
       CGSSCO - Condition number estimate.

PARAMETERS
       COND      - REAL
               On exit, an estimate of the condition number of the factored
               matrix.  Must be called after the numerical factorization sub-
               routine, CGSSFA().

       HANDLE(150)  - DOUBLE PRECISION array
               On entry, HANDLE(*) is an array containing information needed
               by the solver, and must be passed unchanged to each sparse
               solver subroutine.  Modified on exit.

       IER       - INTEGER
               Error number.  If no error encountered, unchanged on exit.  If
               error encountered, it is set to a non-zero integer.  Error num-
               bers set by this subroutine:

                -700 : Invalid calling sequence - need to call CGSSFA first.
                -710 : Condition number estimate not available (not implemented
                       for this HANDLE's matix type).
