SUBROUTINE SGSSCO ( COND, HANDLE, IER ) INTEGER IER REAL COND DOUBLE PRECISION HANDLE(150)
Oracle Solaris Studio Performance Library sgssco(3P) NAME sgssco - General sparse solver condition number estimate. SYNOPSIS SUBROUTINE SGSSCO ( COND, HANDLE, IER ) INTEGER IER REAL COND DOUBLE PRECISION HANDLE(150) PURPOSE SGSSCO - 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, SGSSFA(). 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 SGSSFA first. -710 : Condition number estimate not available (not implemented for this HANDLE's matix type). 3rd Berkeley Distribution 7 Nov 2015 sgssco(3P)
