cgssco(3P) Sun Performance Library cgssco(3P)NAMEcgssco - 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).
