Oracle Solaris Studio Performance Library zgssuo(3P) NAME zgssuo - Provide general sparse solvers SPSOLVE and SuperLU a user-supplied permutation for ordering. SYNOPSIS SUBROUTINE ZGSSUO ( PERM, HANDLE, IER ) INTEGER PERM(*), IER DOUBLE PRECISION HANDLE(150) PURPOSE ZGSSUO - Provide general sparse solvers SPSOLVE and SuperLU a user-supplied permutation for ordering. Must be called after ZGSSIN() (sparse solver initialization) and in place of ZGSSOR() (sparse solver ordering). PARAMETERS PERM(NEQNS) - INTEGER array On entry, PERM(NEQNS) is a permutation array supplied by the user for the fill-reducing ordering. Unchanged on exit. 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: -201 : Failure to dynamically allocate memory. -500 : Invalid calling sequence - need to call ZGSSIN first. 3rd Berkeley Distribution 7 Nov 2015 zgssuo(3P)
