NAME

zgssco - General sparse solver condition number estimate.

SYNOPSIS

 SUBROUTINE ZGSSCO ( COND, HANDLE, IER )
 INTEGER           IER
 DOUBLE PRECISION  COND
 DOUBLE PRECISION  HANDLE(150)

PURPOSE

ZGSSCO - Condition number estimate.

PARAMETERS

COND - DOUBLE PRECISION
On exit, an estimate of the condition number of the factored matrix. Must be called after the numerical factorization subroutine, ZGSSFA().

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