Name

dgssuo - plied permutation for ordering.

Synopsis

SUBROUTINE DGSSUO ( PERM, HANDLE, IER )

INTEGER           PERM(*), IER
DOUBLE PRECISION  HANDLE(150)

Description

Oracle Solaris Studio Performance Library                           dgssuo(3P)



NAME
       dgssuo - Provide general sparse solvers SPSOLVE and SuperLU a user-sup-
       plied permutation for ordering.

SYNOPSIS
        SUBROUTINE DGSSUO ( PERM, HANDLE, IER )

        INTEGER           PERM(*), IER
        DOUBLE PRECISION  HANDLE(150)


PURPOSE
       DGSSUO - Provide general sparse solvers SPSOLVE and SuperLU a user-sup-
       plied permutation for ordering.  Must be called after DGSSIN() (sparse
       solver initialization) and in place of DGSSOR() (sparse solver order-
       ing).

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 DGSSIN first.
