dgssco
dgssco - Condition number estimate.
SUBROUTINE DGSSCO ( COND, HANDLE, IER )
INTEGER IER
DOUBLE PRECISION COND
DOUBLE PRECISION HANDLE(150)
DGSSCO - Condition number estimate.
-
COND - DOUBLE PRECISION
-
On exit, an estimate of the condition number
of the factored matrix. Must be called after the numerical
factorization subroutine, DGSSFA().
-
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 DGSSFA first.
-710 : Condition number estimate not available (not implemented
for this HANDLE's matix type).
